Yes, I agree with all those reasons. But none of them bother me
because I don't care about any of them but the last. AND a 30S-1 can
be run the legal limit, no mater what the spec was at the time. The
4CX1000 can easily handle 1500 watts output at a plate voltage of
3000.
As far as the SB 220, yes that is a good choice as is the 30L-1, both
are going UP in value, not down.
