Tubes Asylum

Questions about tubes and gear that glows. FAQ

I just got in several JAN Raytheon 5751s all with early 1960s production dates. These tubes have black plates with windmill getters. They are of the double mica variety. Joe's Tube Lore only talks about the triple mica type. Just curious to see if anyone on the Asylum has heard these double mica types. Thanks!
