An old FT-902DM, with a pair of 6146's,
only give me 55 Watts out on 160 meter.
All other bands some 90 Watts out (into 50 ohm dummy load).
Plate & Loading (also Preselect) normal settings.
Aligned TX mixer/driver & final, following SERVICE MANUAL.
New tubes - all three - didn't help.
Now I need your help, Please!
Maybe the FT-902DM never gave more on 160?
