Just ordered some 6922 tubes and Ecc 83 s for the cat phono section , i have not been able to sell the Ultimate mk 2 (or "pre" legend whatever it is )and buy a real legend .
I am now gonna try to make the phonostage a bit quiter with"better " tubes , ive ordered 3 pieces of 6922 genelex gold lions and GL ecc83 and tungsol ecc 83 tubes , i might also buy a extra step up someday for mc s as well
See if it works , i quite like the pre and dont want to let it go on the cheap
You might think about some 60-70s Tesla ECC83s. They're better than the ones you've listed (I've just finished doing a comparison of different 12AT7 and 12AX7s in a phono stage am reviewing!). Much like the Tele sound. I find the GL ECC83s just big and bold and tubey and very closed-in sounding. The Tungsols would be my second choice. Don't ever try the JJ/Teslas.
