RE: Amperex 5687 with gold pins, another OGR special

Yes, i mentioned that he says GE in one small part of the ad. We all know that Amperex used gold pins on many of it SQ tubes but no one has run across any 5687 Amperex. And really why would they since they marketed a tube that was even better the 7119 which was also made at the same time in the usa as well. My MFA M75 PP 6550 amps uses the 5687 as the driver tube. 'when i bought that amp 25 years ago, i started collecting every 5687 type, tung sol, ge, rca, sylvania, 7044 type, 7119, and 6900. I NEVER ran across an Amperex gp 5687. None of the members here have mentioned seeing one of those as well. I for one am very dubious, i think others are too.
