WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
How about the Freed # for the Citation II power transformer?
(assuming they made that too) Might as well get the whole setup.
I would also suggest asking Electronic Trans. Co. if they could increase the 6.3 VAC winding current rating a little (another 0.3 Amp). Could use 6197 tubes (0.65 Amp htr.) instead of 12BY7 tubes (0.6 Amp htr.).
Well it never hurts to ask.
But it looks like they don't have the information on the old HK numbers.
They do however have the ability to make the iron listed in their catalogs.
So if you look here> http://bit.ly/2LdhhnR
Those are readily available.
I ordered a QGA-42 which is a 100 watt 5K ohm output transformer and it looks great !!!
