The high mu driver (in a two stage amp) is dependent partialy upon the mu of the finals.
To have a lively sounding amp at low listening levels, with a mu equals 4 or 5 (typical DHT) as Finals, I like to see about a 70 mu to 100 mu front end tube.
If you use a mu of 20 tube, (of which there are many nice sounding tubes ), it will never have the JUMP factor that I like to have in a DHT amp.
I am not into tonally correct but lethargic amps. I do not want to only hear it correctly when the amp is pushed. I want the amp, for long term listening pleasure, to be tonally correct and as lively and vivacious as all get out.
I need an email from you so I can have an address to send you the new power supply design data.
