    The Raytheon tubes are the ones doubled up using adapter on each driver tube spot? Where do you get an adapter like that? And what is the #/model name of this tube?

    I recently got a WA22 w/complete NOS tube set, but only now, after the fact, starting to learn about other possibilities. So your posts are intriguing, to say the least!

    The adapter can be obtained from east bay.

    This is just for fun. The nice NOS EU tubes of this kind are no longer cheap.

    You should try the "traditional tubes" before getting these.

    PS I learned you like SS for your LCD-3F too. Is that true?

    Thanks for your advice. It sounds pretty rationale/reasonable to me...

    I had a pre-fazor LCD-3...an old model w/the lower impedance (they upped it in later models). This was months before I got the WA22. That was a lovely headphone and it sounded pretty amazing on the V281.

    Too bad I can't hear it on the WA22...that probably would be off the charts sound.

    Both @leftside and myself had used the LCD-3F with the WA22.

    I am using clear-top 5998/WE 421A as power tube.

    Raytheon 6J5. Doubled up using one of these adapters:

    Honestly, these tubes sound great. I prefer them over most 6SN7's.

    Not just for fun :) Now you have the chance of using GEC driver tubes in the WA22 for much cheaper than the B65.
  7. leftside
    Yes sounds great in the WA22 with those power tubes. The LCD-3 definitely appreciates the extra gain of the 5998 tubes.
  8. attmci
    I will let you take all these"B65". LOL

    Here's the WA22 with a quad of RCA 76 tubes. Straight away I noticed slightly more warmth with these tubes, but unfortunately for us LCD owners they are lacking a little power. I'll try with the Focal Stellia next week.

    I've enjoyed your past posts as I work my way through this very helpful thread. Picked up a very new/barely used WA22 a couple weeks ago, still burning that in. It has all NOS tubes the 1st owner put in.

    I'm heartened to see a post about 6C8Gs. I'm running an inexpensive pair of them (RCA JAN 6C8G) w/Woo adapters. The look is killer, if I may get all shallow for a moment.

    The sound of this amp is quite a gut-punch to me, as w/one exception (WA3 for high impedance HPs), I've used only SS amp/preamps IMS. This sound is quite lovely to me--biggest/best midrange I've heard since my big/bad 2-channel days (all tube then).

    I'm sure the present NOS rectifier (Mullard CV593) can be improved upon. Have my eye of a Mullard/Blackburn GZ34. My objective is to bring the bass up a little bit. It's all there, just not quite at the level of the mids.

    It looks like an early, automated marshmallow toaster mechanism.

    Apparently I'm not the only one who gazes into the glowing tubes of my WA22 like a perfect wood fire in a fireplace...

    Here are some tubes with a nice glow. WE422A, GEC 6J5, GEC 6AS7G:


    WE422A, GEC 6J5, WE421A:


    I'll have to dig up some driver tubes with a nice glow as well for the complete "glow look".
