Leo Fender began building guitar amps before he started manufacturing guitars.
The first of these amps were the K&F models, which were produced between 19.
5B6 Bassman amplifiers had two 6SC7 or 6SL7GT pre-amp tubes, two 5881 power tubes and a single 5U4G rectifier tube.
It was designed to generate 26 watts at an 8 ohm impedance load, and offered a cathode-based bias.
