Tubes Asylum Questions about tubes and gear that glows. FAQ |

I have had it! I purchased a bunch of long plate grey and black 12AX7s from a reputable dealer and 2 of them have died (no signal at all - the grey long plates) and one has become microphonic (the black long plate)
This is bugging me and now I am down tubes - and this is from a MX110 and an MC240. No other tubes are gone and I recently had the MX110 checked out due to a leaky capacitor. (both these have been rebuilt)
I am fed up here. These weren't cheap of course and I just can't understand why two went dead and the other microphonic. I believe there have been another that went microphonic (a black plate rca) some time ago. I refuse to divulge the name of the dealer because I don't want to screw with his business and to be honest, perhaps it was my fault for not purchasing the true NOS tubes instead of those that may cosmetically may have been challenged.
What currently available will give me great results, and I am looking for warmth and soundstaging and depth. Not a detail freak and also don't mention the Gold Lions...they sounded brittle to me. I am running these into a set of Tannoy Monitor golds so they need to be preferably on the warm but not dead side.
Sorry for the rant!!! It does feel better!
Paul
