Suggest PPIMV for 50watt MArshall type circuit ?

[hebaton]

Looking for suggestions from some with experience using PPIMV on Marshall 50 watt type circuits
There seems to be s couple variants, what would work best on a "plexi" type circuit ?

complicated but good.. from Marshall AFD100

Isn't that some POwer sacling circuit ? A very different thing no ?

im using Lar -Mar type 2, it is usable over 50%..one note here.. how it is double potentiometer, tracking (correct folloving) between carbon traces from pot1 and pot2 is different through rotation, and you are getting power section out of balance with rotation! you can buy several pieces and check with the multimeter differences, and select one which fits the best.. also efect is visuable on oscilloscope

Yup, type 2 (larMar) is the best type in my opinion.

Yep, from what I hear and read, I'm sold on this !
Thanks !

Yea. The type 2 is the way to go. It lets you overdrive the PI (which sounds similar to an overdriven power section). Plus when it is full up it is electrically identical to not even being there.
