    You seem to be quite a wizard in terms of repairing and innovating ideas. I have a Yamaha Portasound PSS 560 synthesizer. It's 35 yrs old and been working flawlessly till a couple of months back. I couldn't play it since I was out of station. I returned last Monday, when I switched it on, I found it working nice but volume has become very feeble. I know how to use multimeter a bit. If you can suggest me, how to start primary checking, I'll remain grateful to you forgood. Defacto, I can't find any trustworthy service provider. Awaiting your suggestion. Thanks. 💕🙏🏽🇮🇳

      You're gonna need to look at the audio amp... you'll need an oscilloscope...

  • @OptimusSkiver
    @OptimusSkiver 11 місяців тому +1

    I've got one of these, and I can't tell if the ambient speaker buzz is just how unshielded they used to make electronics back then, or a short along the line somewhere unfortunately. Otherwise it seems pretty cherry.

      Proper noisy amp in there! May be some duff capacitors

    Great Work! I have a question for ya if you please help me? I have the same keyboard, but when I press any key it makes a hissing sound that is irritating, how can I fix that so that I get a pure sound only without the hiss?

    • @DubiousEngineering

      Oh dear - sounds like you have a small problem with the amp section. You'd need an oscilloscope to trace it back...

    I just bought one, I’m learning how to play it, just a question. I tried different aux cables but I can’t get it to work, the port seems to big to be 3.5 mm. Is it mine missing something or is it a different size port?
    Thanks in advance.

    I bought a used one from a thrift store. It has a constant static hissing or buzzing sound coming from the speaker when it is turned on. I thought it was the speaker but Eleven when using headphones the static hissing noise can be head through them. Do you by any chance know what could be wrong with it?

But in an area where 2 different capacitors are. The board looks a bit darker like of if its stained. It could be that one of them leaked.
