The Russian types are difficult because they aren't in most of the data sources I'm using. It's hard for me to identify which are sweep tubes. But if I have type numbers and can find datasheets, I can add at least some of them.
6P13S, 6P31S, 6P36S, 6P41S, 6P42S, 6P45S. That's it.

Anatoly,
6P13S's and 6P31S's use to be sold als EL36 (the sweep tube one...) equivalents. Are they really, and to which extend?
Best regards!

Correction to the last entry above:

EL236 should read E236L, a long life high reliability derivative of EL36

Thanks everybody. I have updated the list and posted it again here:

http://www.pmillett.com/file_downloads/sweep_tubes.xlsx

It would be cool if GoatGuy could format it again to be readable here

Maybe moderators should move this into the "Magnificent television tubes" thread?

--------------

A few comments/responses:

I cannot find any reference to 6HU5, only 26HU5. So I am not sure 6HU5 ever existed.

I cannot find any data on PL523.

I cannot find any data on EL506. 7868 was purpose designed to be an audio tube.

E130L / 7534 is not a sweep tuibe, but a wideband amplifier tube.

I cannot find any data on 6MB6.

The TV tubes list does have many of these tubes listed, and also vertical amp tubes and others. Still helpful, but my intent was to try and help answer all the questions I get about sweep tube substitutions. Having it in a spreadsheet lets you sort by plate dissipation, or base, or whatever you want.

--------

There are still a few unknowns (highlighted in yellow).

I tried to read the Russian datasheets, but if would be good if somebody (Wavebourn?) can confirm the data.

Anyway, thanks for all your help!

Pete

As far as I know Paravicini's PL519 designs, they weren't Circlotrons, but unity coupled, alike McIntosh's and Gow' patents.


Best regards!

Thanks for this! I've got a pair of 6CU6 that I want to develop into an SE amp, but the sweep tube category is generally interesting.
