PPIV Master Volume Kit

$16.00

If you've got an old Marshall, or other push-pull, non-master volume amp, you already know it has to be cranked up fairly high to get overdriven tone. Unfortunately that also means very loud. With the PPIV (Post Phase Inverter) Master Volume kit, you can install a master volume that will allow you to achieve those overdriven tones at a much lower volume. This MV is based on Ken Fisher's Type II, with the LarMar refinement (2.2M Ohm safety resistors). It is also the most transparent when rotated fully clockwise (maxed, or "dimed"). All necessary components, instructions, and a wiring diagram are included.

Kit includes:
(1) Alpha 250K audio dual pot
(2) 2.2M 1/2 watt resistor
(2) feet two conductor coax cable (2 conductors, 1 shield)
(1.5) foot 22GA 1000V PVC Topcoat wire (for bias supply, color may vary)
(1) Marshall set screw OR Chicken head knob (indicate in dropdown field)
(4) inches 1/8" shrink tubing
(6) cable ties
