Do a google for Harbach Electronics. He sells a direct replacement for
the original fan. Its about the same size somewhat more efficient.
He also has stuff like a soft start up, an electro optical isolator so
a modern transceiver can be used (the original Heath circuitry
switched 115v which is more than modern transceivers can handle.)
I've done all the Harbach mods on my SB-200. He also has a drop-in
replacement for the filter and rectifier circuitry and a replacement
relay.

I can't help you on your meter question.

I have a Heath SB200 that has been modified a bit too much.
Someone replaced the stock fan with a muffin fan and they
cut a big hole for the fan in the RF chamber.

I want to replace the muffin fan with a fan resembling the
stock fan. Grainger sells motor and fan blades for appliances
that look close enough. I just need some data to choose the
right one. Most import is the fan blade size. Second would
be any specs for the motor. Stock motors range from 1/500Hp
to 1/20 HP. I suspect one of the smallers one based on physical
size.

Also the meter seems to stick in a couple spots. I don't
see anything obvious like a bent needle. Any hope of finding
a similar meter that I can move the faceplate? Any place that
can repair meters?

All help appreciated.
thanks
