Post by ValveStorm » Tue Sep 02, 2014 7:54 pm

Hi guys,

A lot of folks were interested in the pots that George used for his PPIMV:
Valvestorm Facebook: https://www.facebook.com/Valvestorm/pos ... 9293143700
YouTube: https://www.youtube.com/watch?v=vypgBhGQwJA

... so at his suggestion we will now be carrying them at ValveStorm:

EDIT: I added some of the installation info for this PPIMV mod to the bottom of the parts checklist here:

The 500ka pot is for the Rich Mod PPIMV II style master (docs here):

AFAIK, the 250k pots is typically used for the Lar-Mar (a different master).

Hi, isn't the wiring / circuit exactly the same as the Lar-Mar, only the pot (500k versus 250k dual) and resistors (220k versus 2m2) values are different?
