These are the REAL THING! Made by Tung-Sol/USA in the early 1960's. Mostly 1964 batch, but still as new in original boxes as the current production re-issue ones. We have both commercial and military stocks. These have long/large ribbed plates and halo-getter on top in almost pristine condition. Matched pairs available.

Grade B for US$65,00/ea w/low noise and microphonics
Grade C for US$40,00/ea w/low noise but slightly microphonic
