Dauner, here you are where the two washers that I told you are located. Hope it hepls
From up to down, HS-J202, not need to change caps, HS-T202, not bad caps, HS-J202 MKII, headphones socket improve compare to HS-J202, but caps...

Hi Dauner, From my experience this type of Aiwa models are not very easy to repair, neither of Aiwa are, but maybe this is a little more if...
Actually the one I was searching for, was the J505, a really nice model, not sound when I bought, I changed the big smd capacitors, now it sounds...
Actually was a bargain, I picked up a lot of three walkman for 50€, an Aiwa HS-J505, an Aiwa HS-PL-77 and the Toshiba, all as non working. I...
Found this gem by chance. It was offered to me as a part of a lot. I'm not a fan of this model, and, to be honest I didn't know anything about it...
These are the resistors that don't have signal. I'm still have waiting for the pre amplifier ic, meanwhile I keep on testing and seeking for clues
Resoldering the q's , now have the right channel working again, and not any sound or beep at the left channel. Testing with an amplifier, pre...
I've found in Ali Express a second hand pre- amplifier ic, for 3€, I have ordered, until it arrives, I try to test all I can. I think it's not a...
I test the pre-amplifier outputs too, the are normal sound
Not any sound at the BBE outputs, I assume the Q's gone bad during the soldering and desoldering process, or the solder is not well executed,...
Left channel not any sound from. By the way I decide to desolder the right' Q channel and test the bad one putting at rhe right channel, , no...
Quick update, I found from an old aiwa a donor Q, desolder the bad one and solder the donor, unfortunately, nothing's change[ATTACH] [ATTACH]
If I understand well , it should have been sound at the red dot of the left side if the Q it`s ok
Let's go for it! Should I check the Q conecting to an amplifier, joint dots and negative to he ground? Maybe this time have to solder both dots...
Another symptom I' ve found, when tape selector position is on metal/ cro2 engaged sound pressure level is good, however at normal position,...
Well, What we got now, BBE out, both dot with present sound, at same level, more or less. Volume input one channel present sound, down dot on the...
Hi @Silver965 , at least some time to spend with the poor hs-pl50. Test done, both channels have signal from the pre amplifier. Testing one...
