Default Adding a parallel feed on DRD

Hi, just wondering if it was possible to add a 'parallel-feed' type arrangement to a DRD circuit, as described by Electra-Print's DRD 300B? Would the choke go before the transformer and before the Ultrapath cap? Where would the coupling cap go?

Finally, would adding a high value cathode cap to the 300B (that was larger than the ultrapath cap) assist in reducing PS noise? Say a value 3 to 4 times larger?

Gavin is really lousy about including any searchable terms in his posts (like parafeed, monkey, drd, 12b4, etc. which are now here so I can find this stuff again), so you would never turn these up, but these two threads (including the links in them) might be helpful:

Will this circuit work?

Serious case of brain fry. You out there Thorsten?
