That's very interesting; I assume that's the power transformer for the preamp? What are the secondaries' voltages and currents?

When I build the Trace Elliot V8 I intend to put it on two chassis: preamp and power amp. And I want the preamp to have its own power supply, so that the stock power transformer on the power amp power supply can handle the extra heater current (at the least) of switching from 8 KT88's to 8 KT120's. But the V8 has 7 dual-triode preamp tubes and 1 driver, then the 8 outputs. So would one of these preamp power transformers suffice, or would I need two?

I have some other big bass guitar amps I might make similar changes to, basically adding a seperate power supply just for the preamp.

The 6K27VF is rated 120VAC 15mA DC and 6.3VAC 600mA. It's only good for two low current dual triodes.
