I wasn't talking about anything radical; just lowering the screen filtering to 32uf, raising the P.I. filtering to 47uf-100uf, dropping the value of the V1a cathode cap from the 250uf to a 1uf-4uf electrolytic, moving the 250uf cap over to V2 and paralleling it across the .68uf/820 ohms at V2, lowering the value of the V1b cathode resistor form 2.7k to 2.2k-820 ohms, raising the tonestack cap to 560pf, and changing the output couplers to .022uf. That's it; still leaving it a PM; if you wanted to re-sell it, it would be easy to put back stock. I just found mine stiff and dark...wait a tick Steve; didn't I buy a modded PM from you back in 08?
