    Thanks for the pinout - that didn't come up in my google search. I have the SM now and it shows the pinouts.

    I don't know what the gain is - the information in my previous post is the most i have been able to find. I will try the KSC945s - I have a couple but will need to pick up some more - there are 12 of them on this board and there aren't any other transistors here - just the capacitors and a couple of resistors which almost never go south.

    Aside from the 537s, I can't imagine what else would be happening on this board. Will probably replace the handful of caps here as well while I have access to it. Thankfully it isn't hard to get to.

    Yeah good idea to do all of the transistors and caps on this board while you have it out. I would be fairly confident that the KSC945's will work if the gain is similar but it will be a bit of a pain to have to cross the legs over for correct pinout.

    All the best and let us know how it all goes.

    Would KSC945C be better? Suffix ā€œ-Cā€ means Center Collector (1. Emitter 2. Collector 3. Base)

    Good call redk9258 :thumbsup:, l had in the back of my mind that you could get some in that orientation but wasn't sure if it was the case for the KSC945's, obviously l didn't study the datasheet enough to see the mention of "C" suffix :rolleyes:. That would make life much easier for ringading's repair l am sure.
