I posted this message on the Amps Site but got no answers. I assume there
must be several
contesters out there using the 77DX. Thanks for any info.
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
