However, there's a website and there's a Mr. Measures around this
forum who has studied much of the mods on '220's and may offer
good ideas.
However, one of the things Mr. Measures discovered is that the filament
transformer supplied with the SB-220 has its own current limiting built in,
so there is nO need for an inrush limiter.
The only thing I've had trouble with on my completely stock SB-220 was the
T/R relay, which is a little slow for modern transceivers. I finally
replaced it with vacuum relay QSK. AG6K (Measures') web site has a lot of
good info. I don't buy his recommendations about parasitics -- my amp is
unconditionally stable -- but otherwise he's pretty sound.
