The Pug
The Pug is an 18 watt circuit for the folks who like the Marshall sound. It's a high gain single channel circuit with hi/lo inputs, 1 volume, and 1 tone control. Most folks buy the "TMB" style chassis (treble, mid, bass) but only use the normal channel anyway so the simpler circuit build makes a lot of sense.
I'm using a set of Heyboer 18 watt trannies and will be building the circuit in a 17”x 6.5”x 2.5” chassis box that also fits the Blues Breaker style combos or the small box head. I do add an impedance selector switch as well as the parallel outputs.
Tubes will be a set of JJs (1 GZ34, 2 EL84, 2 12AX7). You can also substitute a 5Y3GT or 5V4G for different amounts of sag & compression with the Pug.
