Title: Mis-matched but same tubes on sound quality
Post by: charmerci on 29 Dec 2019, 09:42 pm

One of my tubes went bad - so I bought another Sylvania(?) 6CG7 Triple Black Plate which I now realize is different from my others. Will this make a big difference? Probably not as it just being used for voltage regulation in an older AVA Ultra DAC.  :scratch:

Funny, I was wondering the exact same thing.. Today I just received (2) OD3  NOS for the same duty as yours.. Tested them and they were 15 points difference from each other.. But both way above minimum..
