Re: Demco Tubes
You could cross reference them but they won't be any cheaper, you are looking at just over $300 to re-tube that amp. I would stick with what's in it, cross referencing is for when the tubes are no longer available.

Re: Demco Tubes
Too bad on those older amps the tubes cost so much. I know of a few people that take amps similar to that. Depending on plate voltage or if possible to do a doubler circuit and install a GI7b or 6b. Would have to do forced air cooling. But it can be done.
