Description

Pair of RL12T15 Telefunken WW2 15 Watts AF-/RF-Power Triodes, tested "very good"
Description RL12T15: 15 Watts power triode, indirect heated (12,6 Volts, 0,55 Amps), usable as single-ended and push-pull PA in AF amplifiers and as oscillator and PA in RF transmitters. Because of its high possible plate voltage of up to 500 Volts the RL12T15 in the recent years gained attention as possible choice for the single ended PA triode in a triode-based Loftin-White AF power amplifier (see e.g.  http://rl12t15.blogspot.com/). The RL12T15 was developed by Telefunken in end of the "thirties" for military applications and is therefore very robust compared to other tubes. It has a 4-pin bayonet socket, but with different measures compared to the American UX-4 socket. For more technical information see https://frank.pocnet.net/sheets/043/r/RL12T15.pdf
As being the original tube version made by Telefunken the tubes offered have a plate made from grey-plated metal sheet. They were made in the weeks 45th and 47th of the year 1943.
Condition: Unboxed, used, but in good condition without visible mechanical or electrical defects and without gas. The emission tests showed good results:
Measurement of emission according testcard # 1254A of the FUNKE W19 tubetester
at U_plate= 200 Volts, U_g1= 0V, U_h = 13,0 Volts;  I_plate_100% = 53,3 mA :
Results:
Tube  #1:  I_plate = 51,1 mA (= 96%)
Tube  #2:  I_plate = 50,1 mA (= 94%)
