Ill get the layouts posted ASAP.

This crossed my mind, so I thought I'd ask..

Could the PPIMV be applied both ways?

Marshall 2203....
 1) Replace the existing MV with PPIMV ..

 Or
 
 2) leave the existing MV & Vol, and install the PPIMV ..

I've done the first, but not sure about the second..
I do like the sounds I'm getting from this beast...

"What did you decide to do about the PT though?"

Keeping the tranny. Nik & a few others suggested a larger resistor to drop the bias voltage.
I haven't tried to tackle that yet..
Got to figure out how to approach it.

Won't matter if it ac or dc voltage?

None in town... Go figure...

  Will this do the trick?

Ok, I'll pick up a 6 vac tranny at RS..
As for the bias supply... Any suggestions as to what layout I should try to mimick?

Someone suggested stealing 6v from the heaters.. Is this a possibility.,

 Another bias suggestion was for me too look at the Marshall 100 watt bias supply and change the necessary caps and resistors...,

Your thoughts??

This is the HRM BM 100..

Also,, is there a good PT out there that might be more suitable ??

I need some help with the PT hook up...
  Here is what I have done...
My Red wires (350V) are hooked up.. along with the red/y center tap...
Black and Brown (120V) are hooked up....
Green/y is going to the star ground..

 Thats it....
 I need the 6v supply , heaters, pilot.. etc... From the Ceriatone layout, everything on the top side of the tranny...
 Hopefull ythe pics help..

 Thanks!

Sounds great... I removed the original Mv and installed the PPImv... On the preamp side I'm trying to copy an early Princeton circuit... Awesome blues amp!!
More to come..

Great amps with lots of variations.... I've got an original PXX, newer CD-100 and the layout of an original CD-30.....

Gotcha!!!  Almost done. Working on the transformers now, then double check all my wires.... Then we heat some glass!!! Thanks  Todd W,,,

I need some clarification...
At the OD trim pot,
1st... J1,J2 are non-shielded wires, correct?
 
2nd... The two green wires  are also non-shielded??

I wasn't sure if J1&2 were shielded with the wire going to the pot and the shield
going to the jack....

  Any help is greatly appreciated...

I think I figured it out..
