Discussion about the Korg PolySix synthesizer

It looks like you attempted to attach a .gif image but it was blocked. I assume you are talking about the 5-pin 2SA798. This is a dual transistor which the big parts stores don’t have in stock anymore but there are a few smaller places that have them, at bigger prices. You can usually find them on Ebay. I don’t know of any other part that is a direct replacement.

Hello everyone,

Regarding to this subject, thank you all for contributing, i'm also still dealing with a restored polysix having MG issues wich i will describe here later, after i have checked all the common bugs with jed's replacement pcb connectors cables mod wheel and ic's. For now i just have a question regarding that strange transistor with four pins. What possible replacement option is available for this (i assume) nowadays obsolete part ?

Thanks in advance.

  Thank you Nekoma, not bad English at all. Yes the cable socket connectors on the board do look like they were transplanted, it is something to consider.
