Hi folks, I am restoring/modifying a Gibson Kalamazoo Reverb 12 guitar amplifier and need some guidance. This is a 12-watt, hand-wired, point-to-point amp, with 10" 8-ohm speaker, tremolo oscillator and spring reverb tank. The preamp stages are run by 12AX7 tubes, as is the phase inverter and the reverb driver - 3 12AX7 tubes in all. Power output tubes are 2 6BQ5/EL84 tubes. The previous owner updated the amp with a 3-prong power cord. V1 is preamp stage one & tremolo oscillator, V2 is preamp stage two & phase inverter, V3 is reverb driver, and V4/V5 are power outputs. An amp tech here in Seattle looked at the photos of the chassis innards and said that the orange capacitors are bulletproof and don't need changing. But, he did say I should change out the black caps and the big "dual section" capacitors. Another TK'er has offered to replace the caps if I order new ones. Problem is, this is all Greek to me. Can anyone identify the caps in my amp from the schematic and photos below? And from where would I order their replacements? UPDATE: This thread will serve as a running log of the progress of the restoration/modification. Thanks for your time and consideration. Hope all is well with you and yours. Cheers for now. David.
