I was being a little tongue in cheeck, but not much. If I had those Amps, I would look at them and constantly wonder how 421a's sound in them. I have a DV 337SE that only takes (2) and I'm always wondering! I've got 5998's in it presently.

You can get RCA 6AS7G's for way less than $24/tube. But do they have to be matched?

Do you need to remove clothing after half an hour of listening to keep cool around that?

They do not need to be matched luckily. The tubes currently are Sovtek and I would wonder if there would be any changes if manufacturers were mixed? I have not had to change any tubes yet so all is unknown.

Yeah I wouldn't mix manufacturers - it would function fine I'm sure, but not sure what it would get you. The thing to do would be to buy out all the RCA's from someone like Antique Electronic Supply where you can get RCA 6AS7G's for $5 if you are willing to buy them used.

IMHO, the RCA is highly superior to the Sovtek. And that is such an undoubtedly wonderful amp - it would be awesome to hear how it sounds with RCA's. I'm sure it would be even better with Tung-Sol 5998's, but as you indicate, that is a little cost prohibitive...

I bet your EF1 would make a nice glow. The thing is, most of these pictures are long exposures, so it looks like they are glowing much more than they really are.
