[Amps] re Negative lead filtering

[peter.chadwick@Zarlink.Com (peter.chadwick@Zarlink.Com)]

Negative lead filtering works very well. I rectify the volts across the
choke in the screen supply to get the bias: the choke is tuned, too. It
does need a regulator, though. I suspect that if  you used the choke in the
HV supply, you'd need a pretty good regulator, but that's not too
difficult.
