If I survive this storm of the century I might order one or two just to try out.
I never did compare that one resistor that everybody Cuts or changes to see if they use the same one on the AD 203 or the kl203 can't remember the number offhand.
Looking at what RFX75's and 85's go for if you can find one it may not be a bad idea to order a case and sit on it for a while come on.
I'm curious myself, a 29 or 78 with a RFX75/85 should be an ideal channel 19 workhorse as long as you don't encounter the mounting issues that Low_Boy has. If it's no good on SSB it would still be OK, everything on the market doesn't have to be good for all applications in order to be worthwhile (although it would be nice if it did also work on SSB).
It's never easy tying to hide a V8 engine in a Volkswagen...
