hi, I am planning to build up a simple 6V6 PP Power Amp (10W
only PI circuit with a 12AT7 per a channel).
I have a power transformers, of which the secondary tap has
a 125-0-125 120mA tap.

Does it mean that it can provide more than 250V DC
to power tubes?

If not no, can anybody recommend me a hammond pwr for this project?

Thanks.

if you don't use the CT (i.e. use bridged diodes), it can provide approximately 250 x 1.414 VDC (if capacitor input)
