[ETO_Alpha] Converting a 76A to 3CX800A7's Question

[Paul Playford]

I use an 18vac 2.5a transformer (purchased from Jameco) mounted on the back 
panel of my 76A for the filament supply.  I connected the primary of this 
transformer across half of the primary of the stock Alpha transformer in 
series with a resistor that brought the voltage under load down to the 13.5 
volts that the 3CX800A7's require.

I have a question about converting a 76A to use 3CX800A7's.  What does one
  use for a filament transformer?  I see that some are mounted under the 
tube
  deck but I cannot find any 12.6 volt transformer rated at 3 amps that will 
fit.

  Thanks,
