Last Friday i became the proud owner of a SHARP VZ2000. Picked it up for $200 on ebay. It's not often you see one being sold just down the road from you so that you can avoid the perils of shipping.
This is my first boombox and i have gathered lots of great tips from this site, so i thought i would share my restoration with anyone who cares to take an interest.
First off, as is normally the case, seeing it up close was a slight disappointment as it is in worse condition than i hoped. Basically, here's the shape it's in:

Case: Plenty of scratches, stains and marks. Some will come out i hope. Missing 4 sliders. Small ding to left tweeter grill. Volume and tuner knobs looking rather worn. On the positive side, it does have an aerial and a battery cover.

Turntable: Not working. Hopefully just a belt issue! Door opens and closes nicely at least.

Cassette: Not working also. The actual carriage inside for the tape to sit in is broken on one side and dangles down. Not sure what to do about that.

Tuner: This works, surprisingly. And most importantly, it picks everything up clear as a bell and sounds great.

So, plenty of minuses there, but on the big plus side, at least i finally have one of these great units.

I've downloaded an 85 page photo guide from this site on how to strip a VZ2000 down and return it to working order, however, being a novice at this, it could be a bumpy ride.

I've already found a supply of belts and sliders thanks to many of the great members here, so i hope to do this boombox proud (or at least a little prouder).

I'll post a few pics soon.

Cheers

I've got a fairly good front case, tweeter cover and one volume knob (I think!!). Stashed away somewhere. Pm me if you're interested, all I'll charge is postage from Sydney......

awesome , that should be an interesting restoration , i happen to love the vz 2000 you can replace the tweeter grill as they are screwed in from the back but you have to open the box up to get access to them .

Good Morning

Well, i've been up til 5am working on the VZ2000. Here's how it went:

Opened up the how to strip down a VZ2000 guide and immediately realised that it was very user friendly. Second realisation was that i didn't have magnetic screwdrivers, which i can now assure you are a must for this operation. So, just in the nick of time, i get down the hardware store and pick some up.

Back home, i start taking the screws out. Typically, what souns easy is a little more difficult when you haven't done it before and you are conscious of not breaking anything. After some troublesome moments and low level swearing, i get the the door/turntable out. Gently laying it against the right speaker grill, i can now see inside the unit, and i am shocked by how filthy it is inside. This is going to take some serious cleaning.

Slowly i unwind the wires and disconnect a couple of plugs as per instructions, and with great releif i am able to completely remove the door/turntable. I leave it to one side.

Next job is to separate the case. Leaving the tape cassette door open (this is a must) and removing the the power switch (also a must), i start trying to take the front and back screws out. These are a bit of a bitch, and there doesn't appear to be as many in the back as the guide says. So i think to myself that probably some have been removed in the past and not replaced (i'm an idiot).
I begin to try and pry the case apart. It is more difficult than suggested, but i keep trying. Finally, at the point when you start to toy with idea of moving onto brute force and ignorance, i decide to check to see if i have in fact removed all the screws. Being so deep in the unit, it is a little hard to see them. so i get my torch out and peer in. This is when i discover that a couple of holes are full of dirt, Scraping the dirt away, the screws come into sight. I was a bees dick away from disaster, but am back on track now.

Now that i have removed 'all' of the screws, the two parts of the case came apart relatively easily. Here, it's important not to pull it completely apart as you need to unclip the speaker cables at the bottom first. It's very dirty inside, so i get the hoover and Isopropyl alcohol out and start cleaning. The slider controls are thick with dirt and dust, and plenty of little spiders have met their fate inside this case.

Turning to the cassette deck, i can see where a bit of plastic has snapped off the inside carriage, explaining why it dangles down. While i'm fiddling about wondering how to fashion some kind of replacement, i here something drop out of the case. Looking down, i am pleasantly surprised to see the very part that snapped off. Being a relatively clean break, i super glue it back on and leave it to set.

I then change the belts for the cassette. My drive belt pack is a bit short on detail, so i basically have to guess what belts to put in. My method is to look at the old belt, and assuming it has stretched a bit, put a new one in slightly smaller.

Having cleaned up and played with a few things, i now put the case back together. This all goes pretty well as i'm now familiar with how it all fits in.

Now, i'm ready to tackle the turntable. First thing i notice is that there is no belt at all. Oh well, i think, it might have been removed to be used on another unit. Removing the four screws and some wires, i get the platter off, and to my horror, find the old belt, in a disgusting gooey mess spread over the bottom of the platter and around the motor spindle. This is going to be a bitch to clean. Half an hour later, i could confirm that it was in fact a bitch, but it was now at least a clean bitch.

Looking in my bag of belts, i can't for the life of me see one that has any hope of fitting the turntable. Rather than risk it, i decided to use the belt off my spare Rotel turntable and see how it goes. While being a little frustratingly tricky, the belt eventually goes on, and seems an ok fit. The tension seems ok, though perhaps a little on the loose side. Anyway, i put it back together, and then change the tone arm belt for good measure.

Feeling like i'm nearing the end of this adventure, i put the door/turntable back in with relative ease, and quietly pat myself on the back for a job well done.

Now, it's time to test the quality of my work. Before putting any cassettes or records in, i just check to see if they are working. Happily, the cassette now at least is turning and so is the record player. Success!!!! Now, better make sure the radio still works. Switch her on, and oh dear, nothing! Play with the volume dial a bit, but still nothing. Sitting back, getting progressively more worried, it dawns upon me, I didn't reconnect the speaker cables!. Stupid, stupid, stupid! Nothing i can do but pull it apart again. It's now 2am, but i have to finish this.

Second time around, it is all more difficult as the screws just don't want to come out nice and easily. Ploughing on through gritted teeth, i eventually prise the unit open again and reconnect the speaker cables. Then i put it all back together, only to realise that i forgot this time to reconnect the power switch!!!. At this stage i could almost through the unit out the window. But, i refrain from this act, and removing the door yet again, i reconnect the power switch, and then reassemble for the third time.

It's now close to 5am, but i need to give it a test run. First up, thank god, the radio is working, and sounding beautiful. Second up, the cassette is working, but sounds very wonky. i'm not sure if the belts are not right or the tape head is dirty. Either way, now is not not the time to tinker around with it.

Lastly, i turn to the turntable, the main reason i have done all this work as i still mainly play vinyl, pop a record in, and with great relief, it plays. Only issue, it sounds a bit slow, but i'm not sure. I take the record out and pop the other side on, and now, it sounds fine. Perhaps it has righted itself after years of being dormant. Either way, i'm now feeling very happy. I then remember that you can play both sides without removing the record, so i try this, and am horrified to hear the results. Sound quality has gone down to almost zero. It sounds rough as guts. Anyway, i think there are two tone arms to play each side, so if it's just a new stylus that's required, that's no big deal.

So there you have it. My VZ2000 has come a long way in just one long night. It's now clean as a whistle with the record player back in action and the cassette deck hopefully on its way to full repair. I have ordered the sliders from Bredgeo and Alfie has offered me some spare parts to fully restore it to glory.

I have taken pics, but whenver i try to post on here with attached pictures, i am told i need to log in, and then i lose my post. This never happens when i post without pics, so perhaps i don't have sufficient authority to put a picture up. If i can do so, i will post some before and after pics shortly.

Thanks again to everyone on this site who has been so helpful. I seriously could not have done any of this without you.

Cheers

Jeremy

Sounds great Jeremy :thumbsup: always a plus to get these badboys working again ;-) It may take a few times of taking apart and putting back together to get things just right. Important thing is try not to rush because that's when mistakes happen. Hope to see some pics... You should be able to post them :-D

ya i got a 3500 i've been trying to fix and my turntable belt was a glob of sticky mess too. crap got all over the floor and I didn't realize it till i tracked it all over the house and my wife hit the roof. Unfortunately, my TT motor is bad too though, probably the stylus are bad, ugh. like the looks though.

happy teching!

Thanks for the positive replies. I'm loving restoring the VZ2000 with the help of many on this forum.

I'm having a break tonight, but i have noticed that when plugged in, there is a low level humming noise coming out the back. This seems strange as the power isn't even on. When i unplug it, the noise disappears. Is this normal? Does it happen when you just have batteries in it?

And i still can't post any pics even though i've followed some sound advice from another member. Very frustrating as every time i try, i lose the whole post.

Cheers

That's the transformer humming. Some of my boxes do that. As a matter of fact all my Lasonics do it that's why I keep them unplugged until I'm ready to use. The electric company always says even though power is off on appliances there is still a small amount being used and that it's best to unplug when not in use :hmmm:

It could be a 60 hertz ac hum due to old leaky capacitors not doing their job filtering the ac to dc too...

Just run it on battery's ;-)

If it is the transformer, I heard somewhere that you could dip it in a can of laquor that seems to fix 'em too..

good luck!

Thanks for the explanations. It does seem odd that it uses power when not switched on, but i'll accept that explanation and keep it unplugged. I'll get some batteries today and just run it that way for a while. It will be interesting to see how long a set of batteries last with regular use.

Otherwise, i'm now waiting for a full set of sliders from Bredgeo (only need 4 but it's good to have a few spares) and new Stylus (STY-123) from a guy on ebay called andydeals in the US. 2 stylus cost $46 aussie dollars, which is great value i reckon. They're supposed to be authentic Audio Technica, so i shouldn't be disappointed. I'm hoping that a new stylus will fix the awful sound quality which occurs when i try to play the other side of the record. Time, as always, will tell.

Cheers

Wow. I've been trying to post pictures for days without success, but since switching to google chrome and getting updated Java and Flash player, i can finally show the VZ.

The pic above was taken on the day i bought the VZ home. Here are some more 'before restoration' pictures for you.

Happy to report that today i received the two new stylus in the mail. Getting right down to it, i whipped the old ones off and immediately realised why one side didn't sound too flash. There was basically no needle on it. I've never seen one so destroyed.
Anyway, it was a bit fiddly, and you've really gotta get them snapped in tight or else the volume really depreciates, but the sound is now coming across beautifully loud and clear on both sides. One step closer to full restoration! I can now operate the most distinguishing feature of the VZ 2000, being the linear play both sides record player.
The best thing is that i now know that the electronics are basically in good shape, and i really just need to deal with some cosmetic issues.

Next project is changing all of the belts now that i've sourced the precise belts for this unit. I'm hoping this might solve the tape deck issue, along with a clean of the heads.

Cheers

Hi All

Well i'm back and i wish it was with better news. I wish in some ways i left the box well alone when i got it working first time.

Basically, i have completely re-belted the tape deck and record player, got new sliders, and replaced the front case with one in better condition. This all took a few attempts as i made various mistakes in reassembly, including not realising the bases of the old sliders were still stuck in the sliders controls, and having to dismantle the box again and use a hot pin to get the old bits out.

However, i finally thought tonight that i had finished the restoration, but when i switched it on, i was greeted with an interference type noise coming out of the speakers. It reminds me of when i was a kid and i would fall asleep in front of the TV and be woken by the noise which occured when the station would close down for the night. It's not that loud, but it is very annoying, and makes the box as good as unusable to me. I have cracked it open yet again and followed the speaker wires and checked the connectors, but i can't see anything wrong. I am at a total loss, and am worried that i now have an issue that i cannot fix as electronics and i aren't the best of friends.

If anyone has any suggestions for what i can do to fix this i would be most grateful. Otherwise, this VZ is going into hibernation until such a time that i can find/afford to get a professional to sort it out.

Cheers

Jeremy
