Beemers sold me a quad in November, other than his stash I'm unaware of anyone who has any good ones. My surviving CFamp runs daily. I have 8 of the cheap Soviet tubes also, but they sound thin and a little frenetic in comparison. If I have to back to them I'd rather do the conversion. On the plus side I've acquired a boatload of 12ax7s. I have to wonder what my Lindal blackplates would sound like rolled in.

Man, I'm juicing to mod this bad boy a little more.

Anyone out there run their CarverFest amp on a daily basis? 'sides me?

Its going to be used equipment when I sell it, so it may as well be used equipment when I buy it.

This weekend I'm going to do the 12volt mod so I can roll some of these juicy 12ax7s and 5751s in. So many different flavours. The Teles and the Mullards completing theV20 sale should be here by the weekend. Can't wait!
