Some people prefer to keep their equipment "stock" or at least
functionally stock. The SB-200 was never designed for 1500W
output on CW - it was designed to operate at 1 KW DC input (ca.
700 W CW or 1500 W PEP SSB output).
Pushing the SB-220 to 1500 W CW output (or worse, running RTTY
on the high taps) is a quick way to fry something. Even the
toroidal transformer you recommend is only rated for 800 W!

Run it at the HV side and use less drive and less currents all around.
The CW/SSB switch I converted into a stand-by switch.

Unfortunately, this transformer lacks the primary taps for CW/SSB
operation of the OEM device.

Morning Dick,
If you are not afraid of making a few electrical and mechanical
modifications, I would go with this transformer.

I'm glad I did! 1/4 the cost of most drop in replacements. yet MUCH
better performance!
