Schematic close to 1965 Princeton. Our version of that amp also has an on-off negative feedback switch, and a predominant harmonic switch... the original "Princetons" were predominantly 2nd harmonic distortion... this amp lets you select 2nd or 3rd...2nd is original (fenderie ) while the 3rd setting is more marshally.
It has a 15 watt, FluxTone model 4... ( Celestion Blue Alnico cone)
And finally , it can be used as a controllable extension cabinet for amps up to 15 watts.... in other words you can jack into the "Ext. Amp." Jack from another low power amp and use the FluxTone speaker to tame that other amp.
Take a look at these custom tube amplifiers. The Rat Rods are 1.5 watts with 12AU7 power amp. 2 stage 12AX pre-amp with switchable drive stage. 5Y3gt Tube Rectifier. 8/4 ohm output. Transformers are made in U.S.A. and Canada. Turret board construction with ceramic tube sockets. All hand wired by Rick Braman in U.S.A.
This is the Swart amp used in many of the cuts on our "Tones" page.
