[AMPS] AMP Supply Co. LK-800A

[Jim Riff]

I am looking for someone familiar with the Amp Supply Co. (Dentron),
LK-800A linear. It has (3) 3CX800A7's in it and a huge Dahl external
power supply.

I am using it on the WARC bands and it loads to 1500W, but at 1KW the
tuning is drastically different than at the 1.5KW settings; is this
typical?
I am not using a tuner, but the SWR is < than 1.5:1.

Also, how do you evaluate if all three tubes are working to spec when
they are connected in parallel?

Thanks and 73's,
Jim, K7SC
