Hello All,

 

Thought I'd introduce myself and my (small) vintage boombox collection here. :cool:

 

I've uploaded pictures of my nice huge Clairtone 7979, looks pretty good considering it's a dumpster find.... :w00t:

 

Another find is a nice mint Realistic 14-771, rebadging of a Sony CF-515S, see the pics of that too.  Makes a lot of noise for it's size, used it down at the lake all summer last year while I was repairing my dock.

 

Yet another one I got at the dump many years ago is a Panasonic RX-5250 (LS??).  AM/FM bands only, no SW, worked well after I cleaned the speaker plug, even the tape deck too.  It's still in pieces after I took it apart to clean it up, was a filthy mess.  I should look into putting it back together, seems the value has appreciated since I got it lol!

 

I also have the following two:

http://www.stereo2go...05804sears20204

http://www.radiomuse...05lcfsw505.html

 

The Sears 20204 one was the first one I ever got, my first venture into the world of 'HiFi' (after my walkman at least lol, this one had some power!).  Wasn't much left of it when I got it, was already more than half wrecked, but it still works, hanging on by the teeth so to speak.  The Sony I don't think you'd call a full-fledged boombox on here, they were getting small by then.  However if anyone's interested I'll take pics of them.

 

 

Obviously my pride and joy is the Clairtone - boy does it sound good!  Pretty good cosmetic shape, not perfect but not too shabby either, have all the buttons except one, amplifier works perfect.  I'm going to print myself a cardboard copy of the applique around the cassette door, then it'll look a whole lot better - you can see a rough draft in the 2nd pic, still working on it. 

 

>>UPDATE:  Since starting this thread I've managed to repair the tape deck 100%, works great!  Also printed myself a cardboard copy of the aplique around the tape door, looks so much better.  See below for pics of both. :-D <<

 

Tuner is a bit intermittent, going to look for a bad solder joint - AM and SW work fine, but the FM keeps cutting in and out if I push or pull on the selector knob, tuning keeps drifting all over the place, and the microphones keep cutting in and out of the signal - weird.  Also going to debug the tape circuit today, motor ran perfect at first then stopped.  I've got it down to a couple parts on the PCB, wrote myself a mini-schematic of the motor power circuit, proud I was able to figure it out for myself.  Bought a few components on eBay, I'll keep you updated here how the repairs go.

 

I really like the full complement of controls inputs outputs etc, and he digital clock with alarm is a nice touch.  The touch-sensitive tuner knob is a very novel feature, took me a little while to figure it out, and the power plug polarity affecting it too.  I was amazed to find it's actually worth several hundred dollars, hard to believe!
 

To close, here's a tip I learned about the Line-In:  I learned if you want to select the line input, make sure all 3 selector buttons (Radio,Tape,Phone) are popped OUT, so NONE are selected.  The Line-in is direct and always active, so none of the buttons have to be selected.  You can even 'mix' signals together by pushing one in with a line-in source present.  You get a lot of hum if you select the Phono input, which I did at first thinking that was the Line-In button.  It's designed for a magnetic cartridge so has a very high gain, and needs to be grounded.  That's why if you ground the jacks with your finger the hum goes away. 

 

Hope that was entertaining if nothing else, all the best! :clap:

Welcome bellarmine!
 
Look another date code! :yes:
 
Rather than hijack this thread I'll create another about it.
 
BTW, do you mind if I add the above picture to the date stamps archive?
 
Go!

Thanks for the welcomes MKS and =ML=!  Yes there will be more pics coming, especially when I get the Clairtone applique fixed up. :yes:

 

About the date code ML, by all means I'd be more than pleased if you used it, put my box on the map lol.  What is the date stamps archive saving, a database of numbers for different models?  Also, can you tell what year my box is, just curious.

Cheers! :beer2:

Here's a quick update.  I've managed to repair the tape motor circuit, the tape player works great now!  Boy does it run smooth, program search and cue / review, rock steady speed! :-D   Now just the auto-stop system and the tuner board intermittent to worry about, not bad.

 

Here's a few pics of my repair station, tape player running (notice the blurred LED run meter), and the new parts and 'shrapnel' I had to replace off the tape player circuit board :lol:

Hi Everyone,

 

Quick update, using a schematic I managed to debug and repair my Autostop circuit!

 

Found a bad SCR controlling the solenoid, ordered a new part on eBay should arrive any day now.

 

See the pic of the circuit board and all the parts I've replaced to fix the motor and auto-stop circuits.  I made two simple scheamtics for the motor and auto-stop circuits, if anyone needs them let me know.

 

Also, check out this pic I found of 14 Sharp 777s in a row, boy nice box but certainly NOT rare lol!  I found a seller on eBay who has sold 50 - 777's in the past year, averaging $600 each, several for over a thousand (!), and that's just a quarter of his feedback!  Wonder where he's gotten them all from, it's like finding a few hundred running used 1960 Ford Thunderbirds, and selling them off - I mean those boxes are 35 years old, where have they been bouncing around all these years...??

 

Cheers, :hooray:

Thanks for the thumbs-up Boombap, appreciated!  I'll keep you folks here updated when I get the new SCR in the mail.  Nice you have one as well, you should upload a few pics of it...... :yes:

 

By the way, about your clock maybe I can try giving you a few tips to help out.  Does the light bulb around the LCD come on along with the tuner light when you press and hold the 'Lamp Manual' button?  We could talk here or I could send you a PM if you wish Boombap.

 

Cheers! :-D

Hello everyone,

 

Been a while since my last post, been busy with Spring chores.  It looks like Spring has FINALLY gotten here, it was really starting to get me down near the end.... :yes:   I thought last year's Spring was late, I've got a movie of me driving my boat around last April 13th commenting how some ice was still left.  This year the lake was still completely covered 2 weeks later than that, boy am I glad it's over! It's sure been a brutal winter, that's the word for it.  My Dad actually said he has never seen a winter with so much snow before, and he's been here over 30 years.  At least it's always nice and warm with our woodstove, we don't have to abandon house if the power goes out, can cook and save thousands in electricity too. It's now 65F outside, really enjoying it after all that lol.

 

Anyways, latest update on my Clairtone 7979 repair work:  I received a new replacement SCR for the Autostop system a while back, installed it and that's fixed, so now the tape deck is 100% operational, works great!  See the pics of the new SCR in a bag and installed, beside my homemade heatsink for the motor Transistor I replaced.  I've played over a dozen tapes in it, autostop works everytime.

 

I've also got the missing aplique panel around the cassette door done, pretty good job if I say so myself!  Started with a photo of Hemiguy's front panel (thanks Hemiguy!), cleaned it up, tweaked it, printed it out a couple times (see 1st attempt, close), added a few personal touches - color logo, black Auto Search text, and printed this final copy, all sized perfect.  See what you think, can hardly tell the difference, even the color is close, my Dad's color laser does a nice job, and the ink won't run if it gets wet..... :-D

 

I've included the jpeg image of all my hard work inside a ZIP file for anyone who wants it - I'm probably the only one missing this aplique lol (see smaller preview image).  Be sure to print it out with EXACTLY the settings shown below, so it prints at the right size (see last picture).  I'm afraid Windows Paint won't do, use Photoshop, or  Faststone Image Viewer, great freeware program (http://www.faststone.org)!  Might have to trim the bottom and right sides very slightly, all the holes are spot on, enjoy!

 

Width:            7.93 inches / 2379 pixels
Height:             5.4 inches / 1620 pixels
Resolution:    300 dpi (dots per inch)

 

Cheers! :hooray:

Also, here are a few pics of my other boombox as promised, a Sony CFS-W505.

 

Needs some cleaning up, the tape decks work fine.  Amp works but doesn't seem very loud, have to turn it up most of the way to get a comfortable listening level, maybe that's normal with this box?  Biggest problem is the tuner buttons don't all work, particularly the Tune Up / Down buttons - groan lol :lol: .

 

It's actually in pretty fair cosmetic condition, with some cleanup it'd look great.  Anyone have some advice on the tuner?  If anyone's interested I'll consider selling this one, as I don't need that many boxes, and it'd give me some money to buy a nicer one lol :-D

 

Cheers!

Thanks for the comments Lasonic, appreciate it!  Yes, I am pleased with how it came out, considering it got thrown around in the bin, it's actually in good shape considering.  Don't know if anyone will ever use my aplique file, but you're all welcome to it!

Loving that Clairtone - what a fantastic find and what an amazing fix you have done on it - I'm looking in my local dumpsters from now on - much better than ePay :-)

Thanks JT and LED, appreciated!  I've learned a lot repairing it, which is important too.  Never knew about Clairtone at all before I found it, never dreamed it was so rare, wonder why whoever threw it out?  When my Dad saw it, he told me when he was younger he once used a receiver chassis out of one of the original Clairtone consoles for a few weeks, he still remembers the triangular knobs lol.

 

Best wishes in finding one LED, I guess they are more plentiful here in Canada, Clairtone being a Canadian company.  Unfortunately that dumpster location is closed down for me now, new attendant calls the cops on you if you want to rummage around - armed guards for garbage duuuh!!- a friend says just keep smiling, keeps them wondering what you're up to lol.  Be grateful if you have a dump nearby you can rummage through, they're becoming as rare as a 7979 haha!  Fortunately there's another dump close by I'll be trying soon, wish me luck.

 

Cheers!

Thanks Blu, Riker and mancardo, much appreciated!  Yes, that decal was fun to make, and so much more fun to see once I stuck it on, no-one ever notices it's a printout unless I point it out.  Also I learned a lot repairing the cassette deck, makes it mean a lot more to me than if it had just worked at the beginning.

 

Also Vintage Man, you're welcome for the help, anytime.

Hello All,

 

Thought I'd introduce myself and my (small) vintage boombox collection here. :cool:

 

I've uploaded pictures of my nice huge Clairtone 7979, looks pretty good considering it's a dumpster find.... :w00t:

 

Another find is a nice mint Realistic 14-771, rebadging of a Sony CF-515S, see the pics of that too.  Makes a lot of noise for it's size, used it down at the lake all summer last year while I was repairing my dock.

 

Yet another one I got at the dump many years ago is a Panasonic RX-5250 (LS??).  AM/FM bands only, no SW, worked well after I cleaned the speaker plug, even the tape deck too.  It's still in pieces after I took it apart to clean it up, was a filthy mess.  I should look into putting it back together, seems the value has appreciated since I got it lol!

 

I also have the following two:

http://www.stereo2go...05804sears20204

http://www.radiomuse...05lcfsw505.html

 

The Sears 20204 one was the first one I ever got, my first venture into the world of 'HiFi' (after my walkman at least lol, this one had some power!).  Wasn't much left of it when I got it, was already more than half wrecked, but it still works, hanging on by the teeth so to speak.  The Sony I don't think you'd call a full-fledged boombox on here, they were getting small by then.  However if anyone's interested I'll take pics of them.

 

 

Obviously my pride and joy is the Clairtone - boy does it sound good!  Pretty good cosmetic shape, not perfect but not too shabby either, have all the buttons except one, amplifier works perfect.  I'm going to print myself a cardboard copy of the applique around the cassette door, then it'll look a whole lot better - you can see a rough draft in the 2nd pic, still working on it. 

 

>>UPDATE:  Since starting this thread I've managed to repair the tape deck 100%, works great!  Also printed myself a cardboard copy of the aplique around the tape door, looks so much better.  See below for pics of both. :-D <<

 

Tuner is a bit intermittent, going to look for a bad solder joint - AM and SW work fine, but the FM keeps cutting in and out if I push or pull on the selector knob, tuning keeps drifting all over the place, and the microphones keep cutting in and out of the signal - weird.  Also going to debug the tape circuit today, motor ran perfect at first then stopped.  I've got it down to a couple parts on the PCB, wrote myself a mini-schematic of the motor power circuit, proud I was able to figure it out for myself.  Bought a few components on eBay, I'll keep you updated here how the repairs go.

 

I really like the full complement of controls inputs outputs etc, and he digital clock with alarm is a nice touch.  The touch-sensitive tuner knob is a very novel feature, took me a little while to figure it out, and the power plug polarity affecting it too.  I was amazed to find it's actually worth several hundred dollars, hard to believe!
 

To close, here's a tip I learned about the Line-In:  I learned if you want to select the line input, make sure all 3 selector buttons (Radio,Tape,Phone) are popped OUT, so NONE are selected.  The Line-in is direct and always active, so none of the buttons have to be selected.  You can even 'mix' signals together by pushing one in with a line-in source present.  You get a lot of hum if you select the Phono input, which I did at first thinking that was the Line-In button.  It's designed for a magnetic cartridge so has a very high gain, and needs to be grounded.  That's why if you ground the jacks with your finger the hum goes away. 

 

Hope that was entertaining if nothing else, all the best! :clap:
