I replace RFC-2 in the SB-220 with a 25W glitch and never had a problem with it. Bypass it on both sides with a 1000pf 6-10KV disc ceramic....not a Chinese ebay POS either.

         Hello All,



         Sounds counterintuitive as I know the Z-50 in the SB220 & others
who covert them to 6m monoband amps do it but want to throw it out there for
comment.  I've got a Aerotron Navy surplus 3-400 amp I've final got around
to turning into 2x 3-500z 50 MHz monobander & I didn't preplan as well as I
should have for the glitch resistor.  Using a 25 ohm 50w ohmite wire wound
for glitch & the only place with the layout of the tank has the resistor at
90 degrees to the tank coil (Pi circuit) about 2 inches away.  Anyone see
any potential problem with that- coupling, current, etc? Wanted to mount it that way because the cooling fan will keep temp down & won't interfere with
flow around the tubes.  Only other practical option without excessive
rerouting of B+ would put in in a location in the PS deck that won't get the
cooling I want it to have.  Any input appreciated.
