    So what's your take on me doing this to the organ? Will I **** up the internals like the other guy said I would

    If you won't be using it as an organ but more of an experiment then does it matter if you blow it up? Also the output transistors are fused giving you some protection. I do agree that playing clipped audio at high levels will cause problems but you say you will keep the volume down. You are dealing with 1965 technology in a system designed for the living room, not a power head that goes to 11.

    It was my great grandfather's organ so I don't wanna trash it. Can the output transistors be replaced if I do **** em up. Or are they a bespoke thing?

    Wurlitzer didn't use custom transistors, but the specific parts might now be obsolete.
