rufus74pz,
Why is there no bypass cap across the EL34 tube's 340 Ohm cathode resistor?
(Posts # 16 and # 20)
Add a bypass cap across the 340 Ohm resistor, and the results would be:
Higher damping factor
Higher gain
Better low frequency response
Less low frequency distortion
Higher power output
"You should make things as simple as possible, but no simpler." Albert Einstein
For an EL34T (T = Triode wired), be sure to add the following to your schematic, so any Newbies will not make a wiring mistake:
Connect Pin 1, suppressor screen to ground
Connect Pin 4, screen grid, to Pin 3, plate (preferably through a 100 Ohm resistor instead of a wire).
Just my opinions
