The part you circled in red is Q803, an NPN transistor, it's not a diode. D803 is an LED, Light Emitting Diode. In the D803 symbol there are two...
With CAD skills and a can do attitude like this, you might be better off as an entrepreneur! (rather than college) Really impressed.
Oh, I see it, just in front of the tape head. Thanks Emiel
I just checked the autoreverse with welded cassette and I can play side B by flipping the cassette over, so this mech really does sense the metal...
Now I know it's all working I can consider it a bargain, but still was a risky purchase given that a seized motor would have rendered it useless....
The 3.5mm headphone adapter arrived today, £14 delivered from China in 11 days to the UK. Quality seems ok, fits well and works nicely. More...
Thanks all for the replies. I was a bit impatient to wait for a belt from Mihokm, eager to know if the Walkman had any other faults. The drive...
Like many of you I’m always on the lookout for a bargain Walkman and dream of finding one of the rare models for a good price. Well I think that...
Good luck, hope it goes well and all your effort pays off.
I'll be watching this post with a lot of interest. Hope printing the gear works out well for you. If you do consider selling one I'd be very...
Also, doesn't the DC2 have a more powerful headphone output than the others? I think it uses a DC-DC converter to increase the supply voltage to...
Is this capacitor upgrade intended for the DC2? I thought it was for DDII, DDIII, DD30 and DD33?
Before plugging any DC adaptor into your D6C, please read Deb64's post here;...
I finally found time to have another look at the audio problem on my Aiwa HS-PL55, with playback issues in only Normal tape position. Under a...
I checked the components in each channel and they all measured ok with a multimeter. Pin 14 measures 1.5V when the switch is in the Normal...
Hi Silver965, thanks so much for taking the time to look into this for me, really appreciate it. What you say makes total sense. I'll have a look...
No, the Normal path is shown as open circuit in the schematic. It shows NORMAL : 1.5 METAL : 0 which means there must be an internal pull-up...
On my Aiwa there is a tape side switch. I don't have the service manual for the PC202 but there is a switch on the PCB in the pre-amp section,...
Thanks Raul. I did test the switch with a multimeter and it seems to function ok. The distortion is weird, louder on the left side than the right....
Here's the PCB with replaced electrolytic caps (Nichicon UMW MW 4V) The caps in line with the audio outputs to the headphones were replaced with...
