as the saying goes "the King is dead, long live the King! "
Welcome aboard neighbor!
guess you got the "new one" 339 which can handle the pure triodes like 6c5, 6j5....and backward with adapters, pentodes like EF800,80,86...?

 
thanks!
 
i got a really great deal on a 3/4 month used version on ebay, and going through the user's history i saw they bought the '2013' version—is that the one you speak of?

Well what tube types can yours use?, take us a picture?

 

[magnetiq]

oh right, no i think it uses the same tubes as any standard version
 


so you can only use ef80/86 adapters if you have the newest one? I'm almost sure this is, but i'm not really too bothered either way as i'm more interested in 6sj7 currently.

6C5C = 6C5 and 6N5P = 6AS7G. 6C5 are cheap, but I don't know if they're any good.

Does this mean I can replace a 6AS7G with a 6C5G as an output tube in my OTL amp?

You got lovely amp! I'm sure you will not be disappointed but tube rolling....... you'll hate your wallet.
All the new amp purchased directly from Yuking are the triode 6c5 version and he provide some adapter too like 6C5C--->EF86 and I believe 6C5C--->6SJ7GT, RCA 5693... also.
This does not mean that the new is better than old and vice-versa It's more about the universality and reliability the most prone to failure elements was replaced with good ones like film resistors in PS filter or Non-Inductive wirewound resistors in cathode circuit.Yours probably contains some of the upgrades too.
 
The 6sj7gt mesh-shield is best of all no doubt! my favorite.

No sir. You are mixing up the input tube (6c5) with the power tube (6n5p). that's a no go. Like I said: 6C5C = 6C5 for INPUT and 6N5P = 6AS7G for POWER

These tubes are very pretty indeed. Too bad I can't find a hum free pair

R those tung sol 6sj7gt mesh plates?? As mine (totally silent by the way..no hum) mesh plates look different a bit.

 

[Ultrainferno]

They don't look like TS, but they're mesh 6sj7gt

 

[magnetiq]

Thanks WALL-E, honestly that may have bothered me in the past, but i got a stonking good deal and frankly this is a pretty great amp; i'm content… for now

I only know as much as you guys do, having gone through this thread, but i think all mesh plates were made by TS? The ones pictured are Japanese ones, I would imagine made by TS for Hitachi? Skylab would know…

construction isn't the same. Pic belows shows the TS style by RCA (these are mine) and the other pic shows the TS 6SJ7TG. Both are the same and different from these Hitachi ones. They might have been made by TS, but I don't think so
 

 

 

[magnetiq]

oh right, hehe, well that's the last time i try to be an authority on this stuff

Right, thanks, did not read that properly - always on the lookout for new valve options.
