I recently got an Alpha 77DX that was factory refurbished, and would like to
know the working parameters that other users are observing. The 77DX has the
hypersil 4.4kV transformer (not a PeterDahl). I was wondering what you see as
key-up voltage, key-down voltage at full power, how much drive you use, and
grid current on the meter (Yes, I know it reads 2 or 2.5 times real current).
I get about 4000 V down to 3300V with 80 watts of drive and about 200 ma on the
meter. Thanks for any advice. 73 Saul K2XA
