Could someone with Rickenbacker electronic knowledge please help me with this urgent technical question??
I would like to know the unmarked Integrated Circuit part #, which I would like to have replaced on my 1988 - 370/12- string Roger McGuinn Limited Edition Guitar. The guitar is number 236 and the serial number is I17078. The circuit board is being completely restored and this is the only part that the electronic specialists can not seem to identify for proper replacement.
