Just got a used Jack Casady bass in the mail and found the transformer and one small wood screw rattling around loose inside. I've plugged it in and everything seems to work OK so I'll have a go at putting the transformer back instead of fighting with the seller or the post office. I haven't opened it up yet to see how the transformer is supposed to be mounted. Peeking through the f-holes, it appears there is a strip of wood about 3" wide and 1/4" thick glued to the inside of the back, or perhaps it's actually part of the back. I assume the transformer was screwed to that strip of wood and if I remove the pickup I'll be able to fish the transformer back into position and install new screws through the pickup hole. Anybody have a photo or description of the transformer in its correct position? Thanks.
