Please advice. Just bought few Chinese made Valve Art EL156 (octal
base).
The EL156 appears to be a rather high powered TV Horizontal Sweep tube. But the specs given on the data sheet while in PP pentode operation look quite good. The same in PP Triode mode.

About 10 years ago I built a couple of experimental SE amplifiers using TV Sweep tubes. The 6LU8 is a combined pentode/ high mu triode. In SET & SEUL the performance was quite good. In SET it compared well with a 2A3 at a fraction of the cost.

But in SE Pentode operation it was fairly terrible. Not recommended at all.

Anyone wants the dope on the experimental amps contact me direct at-
