Can you describe your antenna(s) and feedline?

My KXPA100 transmits distorted audio on SSB, but works normally on CW and
RTTY.  With 100 watts output, drain current is 11.7 A and supply voltage
is 13.1 V, down from 13.7 V on receive.  My power supply is a pre-MFJ
Astron RS-35A.


The KX3 with which I drive it operates normally on all bands and modes,
with good transmit audio.  Speech compression is off and mic gain is set
to 20.


Should I send the amp back to Elecraft for service, or is there another
problem?
