Rag, does HV read on the HV meter? Yes or No......if no, check both
fuses, one could be bad. If HV reads on meter then fuses OK and R3 OK too.

Ok, if the tube went out then you would have bad swr. not likely that
every bad input NG. Also check the relay, maybe relay when engaged not making
good contact. Need to check relay also.

Hi
Thanks for input. We can try it.
Well, SWR is ok without PTT to the PA… so either pi-filter part or the
tube etc ??

Rag, I think maybe the coax jumper cable from radio to amplifier went bad.
Try another cable. Lou

Hi
My friend LA9TJA have a Ameritron AL-1200 amp which stopped output this
weekend during WPX RTTY on 15m.
1. No output on 30w input anyband.
2. Hi SWR between RIG and AMP.
3. Gridmeter shows 150-250 on any band with 30w input
We may think it can be the input circuit? Any suggestions to me PM la6fja
