hi,all. i have a pair of MQ tfa2004ni that i want to build a pair of amps around, and need to start ordering parts. 275v 55ma. is what my searches have come up with as the ideal operating point for this o.t. running a 2a3. i plan on using the stereomour 2 shunt reg. set up for the driver stage. one for each amp w/ both c4s on the one board.  since magnaquest seems to be out of business. i was planing to order from sowter but they don't offer a 60 ma plate choke.   ( but they will make one.) 30H seems to be  what has been specked in this set up, ( from Paul j. and doc's old  posts) but i was wondering if there is any reason not to go with a much higher inductance (100H ?) I've always read more is better ,but was wondering if there comes a point where the cap value starts to cause diminishing returns.    any thoughts or insight?

Sowter should be able to make you something that's close to 75H at 60mA.
