As a bass player running these tubes in an Ampeg SVP-PRO preamp.
4 x 12AX7 and 1 x 12AU7 tubes, I have to say that my favourite tube in the V1 is a NOS Telefunken 12AU7 (even though technically in the V1 it should have a 12AX7A (7025) or similar).
But my second favourite tube is the Raytheon you both mention. Man what a great 3D/Air/big soundstage, call it what you will, but it has this, combined with excellent midrange definition and clear solid slightly sparkling tops. The bottom end is ever so warm and perfectly compressed. An absolutely beautiful tube.
I dont mind the RCA black plate 3 mica but seriously the Raytheon is the only tube that is in the same league as the Telefunken that I've tried. Dutch Amperex tubes would be my top of the second division choice.
I have to say that I've been less than impressed overall with most of the US manufactured tubes but as I said, the Raytheon is a major league player IMHO.
