Playing with PS
01/30/06 at 18:15:56
 
Hey guys,

I've been reading a lot lately, especially about power supplies.
What I'd like to do is to take the first section of the SE84CSEX power supply, the B+for the SV83 (the 1K50W), and divide it into two, maybe three sections. From what I've read, this should really improve the ripple rejection and lower the noise floor of the amp. Is it really as simple as 40uf,333ohm,40uf,333ohm,40uf,333ohm,40uf and then continue with the rest of the power supply for the 6922 as shown.

Any thoughts or comments are of course greatly appreciated.

Bill

Duncan Amps PS Simulator predicts 8 mV ripple through this stage.

The SE84A had 8 - 33uf 500v sections.
