...gotta love the smell of a vintage Fender!
68 Deluxe Reverb
78 Princeton
Big fan of the Vishay Dale metal film resistors for the plates, silver mica treble caps and Low ESR cathode capacitors.
Both of these amp were brought from Silverface to Blackface specs and then the custom mods were done.
The Deluxe retained it's 2 pot tone stack and had the vibrato LDR desoldered to stabilize that channel's gain.
The Princeton had the vibrato disabled as well, the Intensity pot was swapped with a 10K analog pot and wired as a Mid frequency pot to simulate a Twin Reverb's tone stack. It also has "stacked" caps for the treble part of the circuit, it's a 150pf Silver Mica and a 120pf Ceramic Disc Cap in parallel. They retain some of the dirt of the ceramic with some of the sparkle of the Silver Mica... best of both worlds.
