[Amps] Henry 3k Filament transformer taps

[Robert Morris]

Are you sure it's 240? I'm sitting watching my fancy UPS, on the TV stuff, beep  with 124(248) coming out of the wall.

Lots of stuff in the junk box says 115 if not 110. Bet your transformer is from the 115 days.
You need a variac on the fils, anyway.

Isn't nice we pay by KWH. Don't have raise the price, just crank up the volts....

Hello all you henry radio amp owners. I just bought a  Henry 3k filament
xfrmer off the internet. It is supposed to deliver 7.5 v @ 21 amps. There
are taps on the primary side to adjust output .  I cannot get less than 8.75
volts out. My input voltage is 240vac. I tried all the taps on the primary
side using #1 as the common leg. It is a EC1216a  transformer. I want to use
it for my 4-1000a amp I'm building. 

I suppose I could call or e-mail henry radio but they might be annoyed that
I'm not using it for  one of there amps. Any help would be appreciated. 73
