Okay, I took some readings on the AL-811H.
4 new Chinese tubes installed. HV is 1600V unloaded. Drive ~ 70w
BAND PWR Ip Ig HV
160m 300w 450mA 165mA 1475V
80m 450w 500mA 185mA 1350V
40m 400w 300mA 120mA 1400V
20m 410w 325mA 130mA 1400V
15m 410w 375mA 150mA 1400V
10m 390w 370mA 140mA 1400V
PWR = carrier power read on an average reading meter.
Shouldn't I be seeing more power coming out of this amp ?
Tnx, Hugh VA3TO
Please explain how you are loading the amp, reading the power, and what you
are using as a load. Lou
