In Reply to: RE: Mullard EL38 Triode Curves posted by Paul Barker on April 20, 2024 at 14:01:25
I've used the EL38 in triode in a 2 stage SE amp. Mu is around 16 which makes it possible to even use a DHT driver. I ran that for a while with a 26 in front. Good sound. i preferred the rarer fat bottle version to the tall slim one.
But the EL12 or EL12 Spezial is a superior sound with a bit more gain in triode at mu=18. The EL12n is a cheap version available from BTB.
Here are the curves i was using

Thanks for the heads up. The el12 is highly priced to day but the EL36 with a pip anode in according to the Vade Mecum electrically the same and much cheaper. I guess you are going to doubt that?I did distortion check on the EL38 and the EL36. EL 36 curves used were from Vade Mecum labelled EL12 and 2nd at only 2 watts is 6.7 whereas EL 38 at 3.7 watts is 5.9. 3rd and 4th are not significant in either tube.
I cant really stretch to EL12 over £100 each. But I'll try the EL36 and see what I think. Might take some time. At two watts though its not sufficient for me. But curious. Maybe a PPoutput stage for 4 watts if as SE it shines brighter than the EL38. The extra mu of 18 rather than 14 is handy for a sukuma style. At the moment Ive decided to Sukuma the EL38 as the mu of 14 is sufficient.

True, the EL12 has reached silly prices now. Plus you have to import them from Europe usually. Sometimes you see EL12 Spez with the top cap a little cheaper.But the cheap version of the EL12 is the EL12n. Very close in sound to the EL12. BTB has them new in box at euro 19.90 matched pair

Other European electronics retailers like Reichelt also, euro 25 matched pair.
