I have one of these that I would consider selling for the right price. It has six brand new Ruby 6550's. Currently has one RCA 12AT7 in the phase inverter slot and two Telefunken 12ax7's. This amp is amazing! And I don't really want to sell it but I am in dire need of some extra income and I have an amp that I like almost as much but isn't nearly as desirable on the market. The VR350 really is a special lady and I know a lot of people here would appreciate its beauty. Hit me up on here or at firstname.lastname@example.org if you are interested.
