[Amps] 3.5 kV 2A REGULATED Power Supply: Schematic ?

[R.Measures]

>Requirements for the amp should be stated like this: what degree of linearity
>should I set for this amp, and given that... How do I design the power 
supplies
>and tank circuit to meet the specs I set.  With a the average tetrode, the
>screen and bias supply regulation will impact the linearity far more than the
>anode supply. The place most people fail is in the design of 
>the bias supply (usually can't handle the current properly).  

**  Bias supply regulation is not a factor in Class AB1 since zero 
current is drawn from the bias supply.
