schematic twin reverb
« on: October 30, 2008, 09:22:13 am »
Hi, I'm looking for the schematic (or layout) of my twin reverb silverface (anno 1977) which has 135 watts
rms, it came with JBL speakers d-120.  push-pull master volume
Back panel : hum balance, output tube machting and line recording out.
Well, I've never found the the original schematic of this (maybe rare) model.
So please,if anybody has it..................

A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

I've tone modded three of these in the past 2 months... They do warm up.

I've got one that I am Blackfacing with a Marshall Mod to channel 1. Also upgrading the speakers. The amp in original form sounds thin and weak. These are a lot of work to Blackface if you address the sloppy wiring. I'll let you know how it sounds when completed.
