I have a beautiful homebrew amp made with w/2 4cx250s. The thing is masterfully
made, however there was NO documentation with it. Due to the nature of the
construction (many compartmentalized areas, wiring harness lacing) the wiring
is not easily traced. It's a 5 band amp, but there's no nomenclature on the
metering, so I'm not sure what reading should be what on the function-switched
meter.

Any literature references on two tube designs would be greatly appreciated
as I'd love to figure this out and get it on the air. It's very compact,
has a large blower on the back, and uses the heath HP-24 Power supply
(the one that went with the Kompact Kilowatt).
