  • Kaisertronics Two Knob Germanium Boost P2P

    NOS Philips OC140 black glass germanium transistor

    Eyelet-style Rangmaster circuit with the addition of an adjustable frequency control that allows you to dial in anything from the classic treble booster sound all the way to a fat, warm full-frequency boost. Hand built with NOS vintage caps, resistors, and 60’s era Philips black glass Germanium transistors. These are really versatile and give such a killer edge to an amp that’s cooking.
