Yep, that amp was built in the 60's and its a judge of its quality that the
caps have lasted that long. I have a 2000C here waiting for a rebuild.
That R9 is a surge resistor and doing its job and it could indicate a
shorted tube also.

Bad filter cap. Filter caps were designed to last 6 to 8 years.

R9 keeps going open. Any ideas. It's the center feed to the cap string.
5 ohm 10 w wire wound. I had switched from 75m to 20m and was loading
when
it went down the first time. I had 1450 PEP watts out on 75m SSB before I
switches it. Then I was loading it on my Dummy Antenna and R9 opened.
Help,
