Thanks Carl- I remember your mod, I'm just worried a bit because
this will be much closer to the tank coil than the SB220 had.

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.

Subject: [Amps] Glitch resistor in tank compartment
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.
