I have a 805 single-ended amplifier, and I plan to improve the performance by modifying the circuit.
Here is the circuit. I believed that the 1K resistor at the grid of the 805 was not very good. And others suggested that the 2A3 was not a perfect tube to drive the 805. Is there any circuit which is better than it? Thank you!
