First Amplifier Project, The Lama Kazu 8SE

It started as an attempt to create something like the Kalamazoo Model 1, but with more gain, better tone control and a master volume.

  • Single-ended, ~8W RMS (Clean); ~11W (Full distortion).
  • Preamp tubes: 2×ECC83. Power tube: 1×7591.
  • Speaker: Jensen C8R

Cabinet is FSC-certified pine, finished with Tried & True wood finish (hand-rubbed Linseed & Beeswax product). Grill cloth is Marshall "cane".

(Partly-visible bottom shielding is 6" wide aluminum flashing tacked to cabinet.)

Built in a Hammmond 13.5" × 5" × 2" aluminum chassis box. I forgot to take a picture of the circuit before final assembly, so here is an early image with just the power supply underway, and heatsink hemostats protecting a diode:
