Hi Guys, I hope everybody had a safe and happy Christmas. :yes:

I paid fellow member: Terry (Brian) a visit this week and whilst there, he sold me a very cheap Hitachi TRK-9150W. :thumbsup: I know these models don't get much love here at Boomboxery.com but I love 'em!! :-D He asked me to make a $$ offer. After he heard my offer, he then agreed to accept half of that figure!! - Now that beats Ebay!!! :yes:

To those few that don't know, this model was the first in this TRK 'built like a brick' line. The 9150W is fully featured and has many features not found in the later 9140, 9200 etc models. You get a dial light, twin VUs, digital clock, microphone mix control knobs, tape run indicator lights, Rec Mute switch, Timer stand by switch, Timer Set time and sleep set switches. :-O Unlike the later models, this early bird doesn't have Metal tape capability so you're limited to normal and chrome tapes.

After a good clean, I have found it needs deck belts and the digital display only works when you put a little pressure on the control buttons beneath. The dial light is out, the deck door is a little cloudy and the tape counter numbers have rubbed off too but I've got a parts box that will gladly donate it's counter and crystal clear tape deck door. :yes: The amps are healthy with both channels pumping at equal levels. The tuner AM, FM, SW and line in work perfectly too after a little switch cleaner. :breakdance: During the clean up, I pulled the speakers so I could remove the dust bunnies. Unfortunately, you can't just dunk the speaker front casings in water as the thin, round, silver speaker surrounds are made of paper!!! :-O Except for a few scratches on the left speaker casing, the rest of the unit cleaned up beautifully. :yes: As the original speakers were heavily faded, I swapped in the mint speakers from my 9140E to improve the look. :cool:

Being a W model, this particular 9150 has normal RCA inputs/outputs and phono inputs. :cool:

As a side note, this early model uses the same Rubycon caps as Sanyo used in their similar era 9994 and 9998 models. Of the 3 Hitachis I have from this series (9150W Serial No:00758460A, 9140E Serial No:10234530A, 9200W Serial No:11207201A), this latest addition easily has the best sound quality of any other Hitachi I've heard!!! I got lucky on this one as I think you could go through a number of these models to find a really nice sounding one. :-O

The VUs are responsive but I think I prefer the flashing, super responsive LEDs found in the later models. :cool:
This 9150W looks to have never been opened so all screw threads are perfect and all factory internal wiring is undisturbed. ;-)

It looks to have a slightly different deck to the later models too so it will interesting to see if it uses the same belts etc.

I had it cranking outside this afternoon and wow, it now sounds even better with it's newly fitted, low mileage speakers - heaps of grunty bass and super clear highs from this 9150W! :thumbsup:

Thanks again Brian,

James..... :-)

Beautiful machine! Congratulations! I really love Hitachis, they had some of the best designs. This one is excellent. Great score!
 
Thanks Guys!!

I've completed a full tear down, chassis out and service. I've removed around 100 insect eggs! :-O They were everywhere - yuck!! :sick:
Got the dial light working - needed a new bulb, wires resoldered and a switch repair - all good now!! :thumbsup: It had an FM issue that was fixed by removing the antenna post and cleaning the connection - never seen that issue before!! ;-)

Just got to replace the belts lube the deck and replace the tape head (rusted), sort out the LCD display and it will fully operational!!

This thing sounds great - it easily over powers all my other boxes except the RX-680. :yes:

James.... :stereo:

i have the 9140,and i too love the whole fantastic looks and sound package.totally agree the 9140/50 were the first built like a tank machines that hitachi made.sticking my neck on the line here but quite possibly hitachi's finest sounding 3 piece of all time???? :hmmm:
 
Nice catch! Is the deck working?
They're an easy deck to work on (once you have it out of the case and then the chassis!)
Biggest deck I've worked on - much of the weight of the centre section is the deck. You will need to lube every sliding metal on metal and metal on plastic sliding surface - particularly the pause and timer lever mechanisms.

Good luck with the resto - they are a very strong sounding unit with strong amps and high quality speakers.

James.... :-)

I like the potential. The deck is not priority to work on. I'll see whats what once I get it. Have you ever turn the unit on and get a constant clicking sound? I just got a 9900w unit and played it last night. Blew me away. Played it today and now this clicking (motor like) sound is coming from it. Confused
 
Sounds like it's coming from the deck. Is the deck still working? Loose belts can cause a logic deck to become unable to reset.

Sorry but I've never had the honour of working on a TRK-9900.

the deck is not in operation. It does sound like a motor running. https://www.youtube.com/watch?v=RckiSLM9dEg

Had power to deck pulled. And right channel had a major issue as well. Got call saturday that the work on it is done $110 in repairs. Grrrr. But I do like this 9900. Hope to get it next weekend.

Very fun to work on. All the internals are mounted on one large brick without anything blocked by something else.

The deck is a bit harder to separate, with motor and switch wires snaking around the frame.
As I was looking for a shortcut to getting at the deck keys I noticed you can swing the whole deck out without disturbing any wiring if you unscrew the rear plate ground wire, heads and a pause switch. The 9150W pause key is molded to hold a copper plate that pushes on a switch.

jimmy, do you remember if you found belt dimensions when you replaced them?
The flat belt seems to want to be about 10" circumference but it's hard to know for sure.
