I finished installing my PT today. I measured 448v on the plates, biased at 38ma. Just what this amplifier needed. Really woke up the volume, with added headroom. The original PT only supplied 410v to the plates on a good day. :thumbsup:

Awesome! Here in a month or two I'll be ordering the iron for my 45/100, gonna be putting 560VDC on those kt66s. I'm excited, it seems that everybody loves Marstran.
