WA22 sensitive to unmatched tube?

Discussion in 'Headphone Amps (full-size)' started by brucysn, May 22, 2011.

    Just being curious how much the WA22 requires about the matching of tubes
    Especially with the driver tubes.
    I've got  a pair of Sly 6sn7WGTA brown base from Tubedepot that claimed as matched tube however, they cost the sound significantly shift to either left or right side..... which totally ruined the sound stage. 
    Any thoughts?

    Its a push-pull amp.. matching is pretty important. 
    Do you have a tube tester? Friend with tube tester? For what "good" (or not good as the case may be) tubes cost a tube tester isnt a bad way to spend a few bills. 
    If your coming to the Boston meet next weekend PM me, and I'l bring my tester.
