First off, I would like to say thanks to Doc for allowing this on his forums. I got a little over zealous and bought a couple of pairs of 2A3's from the Tube Depot about a month and a half ago, one pair is doing very nicely in my Stereomour. I have the other pair that I was planning on using in my Paramounts but have decided against this-sooooooooooo, I would like to trade this matched pair of RCA Black Plate 2A3's used for about 45 minutes maybe an hour for a set of 300B, would love to get my hands on a set of the treasure tubes or .................?? PM me if you have some to trade, thanks!!
