Just my 2 cents worth, I bought an old VAC PA 35.35 a while back, and while I liked it, it wasn't as good sounding as I thought it might be, so I set about getting new tubes in it. It had EH EL 34's, and 12AU7's,and 12AT7's. In went NOS Telefunken 12AU7's, 12AT7's, and Mullard re-issue EL 34's, and I'm floored at how this amp sounds now. It's a keeper.
Enjoy,
