Been doing a lot of research on power tubes lately, have ordered a wide selection of tubes including 7236 5998 and rca6as7gs.think they’re all going to arrive before my amp does though!!

Looking at input tubes now, am being confused by the numbering systems. Can the amp take 6sn7 variants? What’s the difference from the 6SJ7? Any recommendations aside from rca 5693, EF80/86 and Sylvania 6sj7 mentioned in thread?

Personally, I have been enjoying Mullard 6080 with Mullard EF86 or RCA 5693 Reds. Very nice bass with either combo; punchy but detailed.

I got some EF86 to 6SJ7 adapters for my 339 and now hunting for EF86 tubes. There are so many ebay listing '6J32P / 6ZH32P / EF86 / 6267'

Are these russian equivalents as good as the standard EF86 tubes?

just got notified that amp has shipped from massdrop! Anyone know how long it took to arrive in previous drops?

Depending on where you are, it takes about 1 week in US

I am not sure whether those Russian equivalents as good as the standard EF86, but I like the Russian 6ZH32P better than the 6SJ7 and 6SJ7GT I have.

Can the amp take 6sn7gt as input tubes? Is there anywhere to find a complete list of compatible tube types.

6as7 is the output tube and cannot be used for signal amplification.

Agree.

Is the first type of tube considered better than the second one in general? I have a few of the second type, but not impressed by them. Hence, I would like to know whether the first type (so called mesh one?) is generally better. Your inputs will be appreciated.

 

[wwmhf]

Also, is the red 5693 significantly better than the black 6SJ7?

Anyone have a link where to buy ef80 to 6sj7 adapters? The one on eBay and aliexpress sold out, only EF86 ones left. Also where to get socket savers and which ones? Can you use the same socket savers for both input and power tubes? Thanks

Can be used, 6336 I have used.

This is news to me. I should try my Cetron 6336b in La Figaro.

What happen to the EF80 and EF86 adapters from the manufacturer? Who was organising these? I had my name down on it but I haven't check this thread for a while and I didn't get any notifications.

Ive read that it might only be appropriate for shorter periods of use, as it draws more current than 6as7 equivalents and might overheat eventually. Let us know how it goes

If anyone could link a site to purchase ef80 adapters and/or socket savers would be much appreciated!
