I have a 8877 tube tester built by W3YQ and designed with help from W8ZR. I
have 25 8877 amplifiers here.
If you want to send it here - I will test for you Dick

Subject: [Amps] Bad 8877?
My HB 6M amp now blows the fuse in the HV line. I opened it up and after
disconecting the anode from the circuit, I get abt 12 megohms from the anode
to ground. I've never measured one before but assume that is not right and I
have a shorted tube. If that's the consensus here I'll open up my HB HF amp and
pull that tube to test 6M.Thanks, Dick NY1E
P.S. I can't complain, I bought the tube for $250 22 years ago....
