Bill, I installed one here about 3 months ago in an SB-221 (same as
SB-220) You need to "make it fit" Does not bolt right up but no big deal to
change hole location. Top screen needs to be cut for relief. Plate voltage
the same. Power output as far as I can see is the same. Perhaps a better
transformer but I did not see any change in power. Lou

I'm interested in hearing from anybody who is knowledgeable about the
SB-220 replacement transformer by Peter Dahl that Harbach is offering --
specifically, wehether it has significantly higher power capacity than the OEM
Heathkit transformer and/or a higher voltage output. They also say you have
to cut a hole in the inside top cover to accommodate its size, which is not
a big deal for me -- but if it isn't a SIGNFICANTLY more powerful
transformer, there's no real reason for me to shell out the bucks for one. I
guess
the short form of the question is: Is this transformer a replacement or an
upgrade?
