Basic Elements of Tube Amp Design & Layout
By Rob Robinette
This is a work in progress.
What do you want? One amp can't do everything but some strategic switches can add versatility.
High or low gain? Tube Amp Overdrive.
Is the amp for you or a "customer"? Too many knobs and switches can be a turn-off for many players.
Must learn to read schematics to study the classics like the Fender 5F6A Bassman and Marshall JCM800.
Basic circuit building blocks.
AB763 blackface: input, gain stage, tone stack, volume, gain stage, phase inverter, power amp, output transformer.
Voicing the clean tone will affect the overdrive tone and vice versa.
Layout considerations & how the Masters did it.
