An organ repairman on the organ forum has told me that these are 2N2926. The organ I have is a one-off DIY experimental microtonal organ (19edo) adapted from a regular Conn organ. I still have not identified the Conn model, because my organ uses all transisters (no tubes) and was completed in 1961, and Conn has no listing of using transistors earlier than 1965.
