Been using 6 x 6BX7 for a while now... I have 2 sets: NOS Sylvanias bought from Jim Cross (he might have more), and NOS Tung-Sols that I bought from @whirlwind.
Never did a comparison, but both sets are really good (and quiet)! Funny enough - I have not rolled them out in a long time. Just changing drivers every once in a while...

Does anybody know what is going on at this point with ESRC .

I know that Stan died, I was just wondering if there has been any news on if his son is going to take over or any other news.
The website seems to be no longer active, at least at this time.

After @Monsterzero posted on another thread last night, I thought I'd go back to the cupboard and give some 6BX7s a go again.

...not a bad experience with these 6BX7s. They are all NOS. I got them some months ago but I have been a staunch Bendix supporter - just using them. I also never nailed a roll with 6BX7s and I had a difficult time originally getting a quiet set (in my amp).

4x Silvertone (label 312, 913). 312 = Sylvania. 913; I think the 9 is likely the year although unclear if 59,69? 13 = 13th week? I may be entirely wrong here, but google says maybe that is it. They also say AAW on them, not sure if that means anything. (actually only 3/4 tubes are date 913, 1/4 is 409)
2x GE 6BX7.

The 4x Silvertones I really didn't like as a 4 pack. I suspect the biggest difference is just adding 2 tubes to get 6 vs 4. I was wondering how much a mixed pack would make? Construction-wise, they all look very similar. I guess it could also be that they need/needed burn-in time?

I really hadn't had much of a good experience with 6BX7s and I am enjoying them at the moment. The seller has 2 more Silvertone 6bx7s which I might just pick up for consistency.

I suspect my @Zachik inspired "dummy plug" which helped reduce the noise floor on my amp was also helpful at getting a set of these enjoyable.

Fun times...

Interesting times. I have found a roll I quite like with these 6BX7s.

6x 6BX7 (mostly Silvertones)
2x 6J7MG (Visseaux)
1x 6N7G (RCA)

The 6BX7 are a bit "biting" (as described aptly by mordy earlier on the thread). They do have nice punch however. I have been rolling around trying to get inputs to compliment them. I had KenRad 6J5s in for a ~1/2 a day and like them with the 6J7MGs too. This RCA 6N7G is more spacious however an the roll works better overall IMO.

If your amp can take six power tubes...it would be very well worth it for people to get sets of 6BX/6BL7 from different manufatcurer's.
It may take time to get nice quiet sets , but still worth it even if you have to buy singles.
Even using four sound pretty darn good and much easier to achieve a low noise floor.
The RCA's don't get a lot of love, but I liked them a lot.

Funny - due to angle and composition, my brain was confused as to why your 6N7G tube has a top cap?!

I like RCAs, too. I think most "haters" say they're too warm or too smooth?
In any case, I like their sound. I think I am easy to please - cannot think off hand of tubes I hate... Anything sounds good out of my GOTL (thanks Glenn!)

Brand question for you tube-smarties. I was looking for some 6J7G tubes. This tube is labeled "AnM (GEC)".

AnM - what is that brand? Is it really a relabelled GEC?

N.B. I'll be avoiding these 6J7GTs

Those are 6J7s... (and I would rather buy a 300b amp if I had $4k to throw )

The 10E is a military designation and I believe the AM with the crown in the middle represents "Air Ministry" - i.e. the Royal Air Force (RAF). The yellow lettering looks more like STC than GEC, but I'm not sure.

Those Marconi 6J7GT's are probably $400 elsewhere if wedgy is selling them for $4000.

No problem, I have a great deal of experience communicating in Typonese.

Were you the lucky person who grabbed the GOTL in the B/S/T forums ?

Unfortunately, no, so guess I'll just continue being patient on Glenn's build list

Hey CD, what are your thoughts on those Visseaux 6J7MG's? They don't fit in the theme of your 6J5 thread, so I'm guessing a report won't show up there (or maybe you could make an exception?).

Related to the 6BX7s, I got a set of 8 Tung Sol's last year and am a big fan of them. I mostly used 4 at a time when I had them in regular rotation (I've been stuck on 6080 and 5998 power tubes for months). They are very spacious and detailed, but need a warmer driver tube complement otherwise they can be too much. They sound very different from using 4 or 6 GE 6BX7's. @Phantaminum hooked me up with a whole truckload of GE's when I got the GOTL from him. They are great too, but I figured I would try a different brand when I got the Tung Sol's. I need to go back to these power tubes soon as it's been a while.

I wonder who the lucky winner was...

The 6J7MG's. There is a polish seller who has a load of them. Pairs for $36. I agree w/ your comment:

(musing: Are they the C3Gs of the output world? I can hear your "I've been C3G'd" and perhaps ... "I've been 6BX7'd!")

The 6J7MGs by themselves are probably not what you would want to use. In combo with other drivers, they add warmth and something else I can't yet name. I keep trying them in different rolls. Today, I have yesterday's roll with just the 6J7MGs removed and I like the roll just about the same as with them. I think that is just because the RCA 6N7G is warm enough on its own. I think of them like the EL32s; good "dual driver" mixer options. I haven't yet found a "killer roll" where they really nail it, however. I think I might at some point. They have made me curious enough to go looking for other 6J7Gs yesterday too...
