What type of an exciter are you using with this amplifier that you need ALC?
Thanks

Hi all,
After a long time of having an intermittent no power out problems on
my amp, I finally figured out the problem was the parasitic
suppression circuit. I had put one of Rick Measures (SK-RIP) Nichrome
kits in it. Not sure if there was a solder joint issue or what, but
went back to the stock suppressor, replaced plate choke (original with
resonance issue on 17 meters) and it works fine. At least 40 through
10. I notice when I tune it up on 80 meters I get a quick sizzling
sound sometimes (very short duration). I assume that is an arc? I need
to get the ALC line back on cause it's obvious it only needs about 75
watts input for full output. New Graphite tube. Have not tried 160 yet.
So could it be a little over driving it on 80 that is causing that, or
if not, how do I narrow down where it is? Definitely nothing burnt
cause I went over it with a fine tooth comb.
