Hello Bruce! At some point I would like to build these mono’s, however I think I would like to put both channel’s into one chassis.
Besides still having 2 output trannys, I would like to use a single tranny for the power supply. My first question is, How many milliamps will we be drawing on the 360v for each channel, so I know what kind of amperage rating I need to look for on a power transformer?

Hi, It will be huge. The steady state draw is just about 300ma per pair. To be safe you will need to plus that up a 100 ma or so. You are looking at about an amp at 360 volts. Big and expensive. Plus likely very heavy ...perhaps 5KG or more. I would be inclined to build two separate supplies on the chassis. The cost might be less.

Good listening
