Hi all,
Got an sb-220 at an estate sale a year ago... just getting around to
checking it out now. It exhibits the following problem: when in rcv mode
(i.e. no exciter), the grid current pegs the meter to the left. HV seems ok
at 2500V. I have removed each (one at a time) of the 3-500z's and the
problem still exists. It would seem that the problem exists somewhere in
the bias supply... any help?
Thanks,
Mark, WA6JIQ
