18-Watt TMB effect loop
I'd like to use the Metropoulos effect loop in an 18-Watt TMB amp. The install between the Treble and Master pots looks pretty straightforward, but I'm not sure about where to pull B+ from and what voltage is available in the 18-watt circuit. I'll need to measure it in my specific amp, but looking at some 18-watt resources it appears the plate voltage on the PI is typically in the range of 150 to 210 volts. Anybody have some references for installing this FX loop in an 18-watt amp?
