Metropoulos Forum

HI guys. I am doing a 67/68 100w and ordered a Mercury Mag # MP100-68 transformer with 460 B+ voltage. I was told by Patrick at MM that this would be ideal for the 67/68 Plexi style 100 watters. Any thoughts? I know the later 68-73 100w versions by Metro shows B+ voltages in the 495-498 range when checked during the power up procedures in the instructions. The 12 series switch takes the voltages way down to the 400+ range. Anybody used the MP100-68? What are your opinions. I'ts been payed for so I guess I'm going to try it regardless. Thanks!
