Four Hour Tube Amp Warm-Up

Same here... With the little soundartist el-34, 4hrs is needed to sound best.

@bolong +1; a weak tube can take a long time to warm up properly.

Where is @tubebuffer these days?
As Confucius say, “Man with strong tube, need little time to warm up.”

After making some adjustments it is down to about a 2 hour warm up now.

Time has passed and the Sophia Electric EL34's are probably technically burned in now. I would say that about an hour and half use/warmup blooms them nicely. However, a couple of weeks ago I accidentally left the tube amps on for 7 hours unattended. When I got home that night and started playing I was taken back to the real, real "bloom." What can I say - there is this everyday operating dimension and then there is the dimension slightly beyond. I am hopeful that electrical theory will one day catch up.
