Thanks for the kind responses folks. The owner came and picked up his amp last night. He was very, very happy with its tone. He claimed that the amp was dark, and broke up very early. He writes music and performs in an original band. He uses no effects, only a clean Tele, straight in. So the end result of this restoration met his hopes. Of course after we demo'd his amp I invited him to try whatever of my vintage amps that he wanted. 2 hours later, we had been though most of them. He asked lots of questions. I poured on the info. I educated him in Fender amps and the heritage of Leo Fender and Co. He was particularly interested in his new and exciting vibrato, now present in his Twin. I pulled his chassis and showed him the roach. I answered lots of his questions about the guts of his Twin. I went as far as making him try all 3 types of Fender vibrato in various amps of mine. Harmonic, Bias Wiggle and LED Roach style. He had no idea, and said he loved them all. In the end the mighty HPTT was turned on and we both shook our head in wonder. He left happy with his amp...I think. I may have wrecked another young aspiring guitar player. It happens. 24 Track we are close, you're right. Could be the same hack in both these amps. We might have a serial amp killer running amok in town. See the black cathode caps? Those are Whale brand. From my experience, I have only found these Whale caps used in Fender amps after CBS took over Fender, early in the game. I believe by 1969 they had switched to White Mallory cathode caps as BobbyZ pointed out. I have read bad reviews about Whale caps, but can't speak from my own experience. I remember reading a story where CBS purchasers saved the company a bunch of money by sourcing cheaper caps from Jamaica. For use in amp assembly at the factory. The story went on to say the quality was poor, but did not name the brand. I often wonder if it were these Whale caps? Mallory makes a good cap and is still around today. Whale? Gone I think.
