I acquired a 1969 Super Reverb silverface, no drip edge, original foot pedal and cover, amp from the son of the original owner, an accordion player, in rural Manitoba, Canada. No one has been under the hood of this amp except me. There are no apparent problems with this amp except 51 years. I will post from time to time on the progress, trials, and tribulations of the restoration process. Cabinet first and then the electronics. Thanks to @Wally, @schmee, @jondanger, and @Andy_B for helping me identify the circuit in https://www.tdpri.com/threads/1969-fender-super-reverb-sf-circuit-id.1067520/ These are some before pictures.
