I have never heard of that tube. Did you already have a set, or seek them out?

EL38 is great in triode - andy evans 02:38:14 09/11/23 (1)
I used EL38 in triode for a while - probably the best pentode in triode output I've used, with EL12n a close second. I don't like using tubes with top caps, but the sound was marvellous. Especially the "fat bottle" ones.

  I just popped in here to see if I could validate my experience with the Mullard EL38 triode set. What you said is my experience. Its not a clone of the EL37 with a top cap. But a different tube in its own right. Dont look for operating points from EL37 and certainly not from the EL34.
  
  Ive had to order a new uTracer. When built I'll trace the triode curves. But I found for now 300 ohm cathode resistor 380v anode volts holds it at max dissipation. 400v and its dissipating 29watts.
  
  I dont get any plate hot spots at 380v.
  
  Its much more lively than an EL84, I like the tone of the EL34 triode but this valve is more live sounding. Foot tapping body engaging live music.
  
  Quad 57's love it. As soon as I tried it I went back on ebay to buy another nos pair.
  
  Im not excited by low power dht's these days. Too polite and boring.

As my op I have been running them for a month or so, with adapters, but my question is: am I doing the bias wrong re EL38 vs EL34 on this particular amp...
