OK guys...this is for real, and here is the story. I have 15 of these. Most are original Blackburn Mullards with the codes on the glass, and an Amperex with codes. I want $150 for the lot shipped. Here is the catch...you knew it was comming...I have absolutely no idea how good these are. I have no tube tester, and absolutely no way of telling how much life is left in these. The only thing that I will say is that they all work. I put each one into the front end of my amp and every one of them fired up and sounded great. I just fell into a bunch of NOS Mullards still in their boxes, so these are expendable. Here is the breakdown of the lot...
10 Mullards...all made in Great Brit with Blackburn codes
2 Jan 12AX7WA
1 Tung Sol 12AX7 (original...not the reissue, probably from the 60s as it has a square getter)
1 RCA Blackplate 12AX7
1 Amperex (Holland, with etched codes)

Unless you have a tube tester, I would not recommend that any of these be put in V1 (phase inverter) of your amps as that tends to be the hardest position on tubes. I don't use any tube preamps for mics, so I don't know how they will perform in that situation.
