[Amps] Gettering 3-500 Tubes

[Glen Zook]

Not the SB-200 or SB-201, those amplifiers use 572B tubes.  The SB-220 and SB-221 use 3-500Z tubes.

Methinks your typing fingers got out of sync with the brain!  :>)

But what if they arc over?  Isn't that going to do some serious damage to the SB200?
If you don't getter them, how about at LEAST put a resistor in series with the B+ to limit the current.
A bad tube will still arc (snap)  won't it?
