I tried that UK valve combo with a VR102 once and it very very airy.  Love how the fat glass gz37 handle the low end. While the 6AS7G gave a big soundstage.   What phone your using with that combo?

Love that combo also.
Running GEC 6as7 and cossor fat bottle
Oh and mullard ecc35

I have the Senn HD700 and it really benefits from this tube combo. The fat GZ37 adds a nice bit of weight and body to the bass and the GEC 6AS7, being somewhat warm and dark (compared to the 5998, for example), helps to tame the 700's somewhat peaky mid-treble. This combo coupled with a Mullard ECC31 is awesome.

When I first started buying ECC31, I could usually pick them up for less than $75, so the cost of an adapter was well worth it especially considering what ECC32 cost. Now that more folks are buying them, the price has gone up, but still they can be often be purchased for around $100, still a good deal. That said, if you already have the ECC32, it probably isn't worth your time and money.

Have you tried the ecc32,ecc33,ecc34,ecc35? From my experience they sound similar. Especially the ecc32 and ecc34.
I still haven't tried an ecc31.

Yeah. I have 32s and 35. Prefer the 35s a bit more.
Ordered a pair or 31s will be here next week.
Probably try some 34s just because. The 33s are hard to find and really expensive.

  Most of the Siemens C3g out there are from the 1970's, with silkscreened shiny black cans. For some time now, I have been curious to discover how the Siemens C3g from the 1950's and 60's compare. And yesterday, I received a such a pair with embossed flat-black cans.
 
 


 
And here, compared to Lorenz C3g from the mid 1960's
 

 
I am pleased to report that they light up and play, but haven't yet had the opportunity to make any comparisons.
 

 
I am interested in your findings Ken....are those Gec 6AS7's in there with the C3g ?

Yes, a pair of GEC 6AS7 and a fat Cossor GZ37 with the C3g.


Nice combo of tubes
I always liked the GZ37 only the WE422 or damper diodes are better.
And the GEC is about the best 6AS7 to me.

Hopefully, when things settle down for me at work...we can get together with our amps

I am on a mission to keep my eyes open for a good deal on the GEC 6AS7
 
Glenn, is there a certain 6336 tube that sounds better or works better in your amp, than others ?

Only get the 6336A or 6336B. Dont get the one without the letter. Their rubbish. They all sound the same except for the Thompson 6336A. It has a different construction.

Thank you, George.
