RE: Power Amplifier link

The kit is designed to work with the original ST-70 power transformer and uses all of the secondaries that it provides. Filaments are all AC. You will need something like 375-0-375 VAC at 400mA, 2 x 6.3vAC at 3.5A (center tap a convenience, but not necessary), and 25-50VAC at 50mA for the front end negative supply.
