Hi Rob,
A simple guess, did you turn the front panel PWR and CAR pots fully clockwise ??

Hi folks,
I am sure this topic has come up before and I apologize in advance but the
kenwood archives lack a search engine. I am a new owner of an 850 and am
new to Kenwood amateur gear in general so I'm in learning mode.
My 850 on sideband won't peak out at more than around 60 watts before the
ALC kicks in. Normally this would not be a big deal except that I drive a
grounded grid cathode driven pair of 3-500s and as anyone with such an amp
knows, it needs more ooomph from the exciter than the ceramic tube screen
driven amps do. Around 100 or a little more watts would be nice in order to
hit 1.2 kw when I need to. I've checked the feedlines and made sure it's
not folding back due to a swr problem, so it looks like the next thing to
try is to go in to the trimpot no. 7 on the tx board and try to dial back
the ALC a bit. I just wanted to check here to find out how common a problem
this is, and if I am on the right track. I have the service manual with the
ALC adj. portion and it does not seem to be too tricky.
