Fantastic 1972 Silverface Twin Reverb came in looking a bit sorry for itself with a metal grill.
I Serviced and modified her and now will nor let her go.. my own No 1 Amp:
- Full recap of all electrolytics
- Circuit modded to AB763 specs (Blackface)
- Normal Channel Modded to a Tweed Bassman tone stack (more gain and not so much mid scoop)
- Reverb and Vibrato added to the Normal Channel
- Original RCA tubes kept but bias modified to be able to adjust bias on each tube individually (not a matched set at all)
- Master Volume Removed and a “Soul” Control added (so you can adjust negative feedback) adjusts the whole attitude of the amp
- 2x Eminence Legend 1258 speakers replaced the too knackered Pyle Speakers
- Most of the preamp tubes needed replacing (they gave out or became noisy during testing)
- New grill cloth put on
- 2 more handles added to make the amp more “portable”
