There was a cool Russian-made tube GU-48. It is high-gain, high power pure direct heated triode with 300W on plate and 10A on carbonized tungsten cathode. I did not hear but it looks like something in the class of RCA 833 tubes. I think Japanese sell the 833 amps for 200-300 thousand dollars. The GU-48 is around $50-$60 and I do not think that it would be worse; in fact I think it might be even better…
