Here you go: http://www.ebay.ca/itm/201511879930?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT     Thank you.  How well does it work in your WA22 ? Any potential issues with 2 6SN7 drowing too much power ?  I would use it in WA2...   it uses same power tubes. 

Mr. left side  what is that adapter you are using for your power tubes?  How can I get one?

Thank you gibosi. I have done some reading about 6sn7 tubes in general but not to many sonic opinions between same manufacturers . I remember VT231 designation was stopped some time after war 1950?  so what would be a worthy replacement for that military RCA ?  how much do they change in sound...

Any significant sonic difference between  RCA 6SN7GT grey glass and  RCA JAN CRC 6SN7GT VT 231 grey glass ? The later one is one of my favourites and there seems to be $30 to $60 gap between the  two.

  Thank you Rick. I see some more responses and thanks to all. Now that I went back to see all listings , none says 6SN7  . That's where  I assumed it was just a variation of 6SN7. Big question here , can 6SL7 be used as direct replacement for 6SN7 ? i would try to stick them with...

Hi guys.   Is there much sonic difference between 5992 and 5991 red base . Most info says all 5992 are made by RCA and relabeled for different companies. How about 5991 ? some of those float around e-bay for much lower price then 5992. Could some one provide some info on this .   Thanks

    Ok this looks better.

Thank you . I should have known better to ask before purchase.

Hi guys.   I purchased something like this " NOS NIB Bendix Red Bank 6082A tubes -tested- 26v 6080 6as7". This was last minute purchase and now I have some doubts . Can't find any info on this tube , well plenty info on Bendix in general but this 6082A and 26V worries me . Is this something...

Hmm... not sure Chris why you assumed  I am trying to cram two of those opamps into my amp . Price of $140 is for a pair ,single would be $70. On the other hand price of $70 is roughly 1/4 cost of new amp . What do you say to WA2  owners buying two 421A tubes costing more then half the value...

Any one tried this one  Burson Supreme Sound Discrete Opamp Modules?    Would those work in M-Stage?  On this page  http://www.partsconnexion.com/opamp_burson.html  it says direct replacement for  OPA627.   Thanks
