Telefunken EF800/CV5092/6BX6 tube. This tube is absolutely new, in immaculate condition and tested for mutual conductance and noise (in our STAM SA47 Mk2).

The EF800 is the milspec/professional longlife, low noise version of the EF80/6BX6.

It is the gold standard for the Miktek CV4 Mk9 Bock Audio 241, Stam Audio SA-47 Mk2, Golden Age GA-47, Perlman TM1 etc.

Please do not use these in a STAM SA47 Mk1! If you are using a STAM SA47 Mk1 please shop for our gold pin EF800/EF860 which we will be happy to  noise test in our mic for you, too (at a modest surcharge)

These tubes are from the late 1960ies/early 1970ies made in the legendary Ulm factory.

You will find the Telefunken diamond <>on the bottom of each tube and the Ulm factory code on the glass.

Each and every tube will be carefully tested before shipping to guarantee best performance.

The tube is guaranteed to be new and unused from professional service stock!
