Yay, you found yourself a genuine Philips CD371 by another name! Check the ebay prices.
Wow !!! Found 4 for sale on ebay Europe. Most reasonably priced is about 100 Euros ! Two sell for 130/150 shipped, and the last one is from a guy on crack who wants 400+++ Euros for it !
Paid 10 Euros for mine !
Jeez...
Now that's the one to concentrate on, forget about the Sony!
Will proved the driver chip a bit as you suggested earlier, then will tell the seller (who was curious to know what was wrong with it) that I need to replace that chip and it's no economically viable, sorry bob...
It shares the same transport and PCB as the CD372 (CD371+ IR remote), 471 (same as 371 but larger case + VFD Display) and CD472 (CD471 + IR Remote).
Wow, you sure know your old Philips !
The only weakness with the CD37x is that the LED display tends to be a bit unreliable (it has a built-in serial interface), not a big deal though because the serial format is very simple and you can get standalone chips.
Oh, thanks, problem already solved then. Just need to bodge the stand alone chip somewhere on the front panel. I hope the chip is not 50 Euros... or I would have to replace it with a tiny 8 bit micro to emulate it. I guess the Philips nerds have already sniffed the protocol and documented it.
I suggest starting another thread for this one.
Yep sure, of course, it deserve a public repair ! I am already very proud of my little Radiola !
P.S. Watch out for ESD on that transport ribbon when unplugged. A metal paperclip slipped over the end is the standard protection method.
Simple and clever.. paper clip, will buy some soon then !
Some more : along with that Radiola, same day I also received another of these "doesn't look like much but it's different than the rest of the crowd and dirt cheap so will buy it anyway, to diversify my experience" .... I got a Toshiba XR-9128. When I opened it, guess what ? Same internals as the Radiola ! Same CDM 4/11 cast resin though this time black not white, and same TDA1541A ! The main board looks 99% identical. Only a wee wider maybe, and the routing of the components, CPU and DAC, in the lower right corner of the board, is a bit different. But other than that.... Clearly one board is merely a slight variation of the other. Date codes on the DAC is very early 1989. Cabinet, like the main board, is also a tad wider. Has IR remote sensor too, and a VFD display not LED. That fits your description of the Philips CD 472 ?
Whatever the model, do you think it might indeed be yet another Philips under the skin ? Or like the Radiola, a plain simple rebadge, and even the front panel is identical to the Philips ?
Paid only 10 Euros for it, and it works just fine, I don't even need to do anything to it ! Detects the CD / TOC in an eye blink, and switches from a track to the next at the speed of light. It's really in tip top shape !
Only thing that would need doing I think, as preventative maintenance, is the rubber belt that operates the tray. Tray opens and closes just fine right now, but the belt looks like it's on its last leg. Very sloppy and with many deep cracks all over it. It won't last another 30 years for sure...
Since it works, I could use it to swap transport with the Radiola to help me narrow it down.
And, some more... still the same day (I received 4 players that day...), I also got another cheap unknown player that I somehow wanted to buy, because the brand name didn't ring any bell to me : "DIGITAL" is the only marking on it. So I though OK, let's see what is this thing.
When I finally had it on the bench... noticed that "DIGITAL" might not be the brand name after all... in the top left corner of the front panel, where you normally see a brand logon, there was nothing but some indentations in the plastic. Maybe the logo came off, was glued and the glue didn't stand the test time ? Don't know. Anywho, at the back of the cabinet there is an ID plate that says " Technics model SL-PJ25, Made in Japan". Ah, a Technics then, not a " DIGITAL", silly me !
I was eager to see the internals, as I have a couple Technics players that feature a swing arm, somehow. So would this one have one ?
.. NOPE.... is it a boring / conventional transport then ? NOPE either ! This thing surprised the hell out of me : it used something weird I have never seen before !!! See pics below tell me what you think !
It looks like a mix, conceptually, of a swing arm and a linear tracking. The pickup does move linearly, in a straight line like a conventional transport, however the pick is not moved using a traditional DC motor with gears and such. No. Here the track is a beefy metal bar on which rides a big coil. When the coil is energized it moves along the track. Pickup is tied to the coil of course.
So it's like a swing arm, no gear, fast moving, and perfectly smooth and quiet. And see the pickup : it's in a nice cast metal housing !
This transport is so original and well built, a joy to look at see moving !
I like innovative engineering and build quality ! I am DEFINITELY keeping that one as well !
Doesn't work though, doesn't detect CD's, and it won't try to spin the disc.
Searched a bit, looks like they call this thing a "linear motor". Makes sense... first time I see one.
Pics of the Toshiba / Philips ? then pics of the Linear motor Technics in a separate message, to keep things tidy...
