UBF89 RFT (RWN) Tube, NEW 10FD12 Pentode Valve

Brand NEW UBF89 RFT (marked with RWN Neuhaus logo) tube, equivalent to 10FD12. Near equivalents - EBF89, 6DC8.
The UBF89 features two signal diodes and a variable mu pentode in the one envelope and sharing a common cathode.
UBF89 is used as a final HF or IF amplifier and detector. Or with a separate detector the two diodes it can provide a delayed AGC voltage. This would give full amplification until a threshold is reached. The high impedance of the pentode supports the case for use with a tuned circuit connected to the anode.
Uf=19V
If=0.1A
Base: Noval B9A

All tubes are from one and the same bulk factory box.

All item(s) will be shipped by registered priority airmail. Typical delivery times are:
EUROPE (All countries): 7...14 days
