I would recommend our custom choke # 04-002. This choke can be supplied for service at 100, 150 or 200 madc. Inductance would range from 10Hy, 7.5hy to 5hy as you go up in dc current. the DCR of this choke is approx 36 ohms.
one thing to be aware of when reviewing designs in the public domain... designers often use "state of the spare parts bin" availability in spec'ing their ironware...
the power supply shown is for a monoblock... with two halves of a 6sn7 and a 300B there is no way you need 250 mils of dc current capacity... and if you notice the power trans itself is not even spec'd for current.
200 mils ought to be more than plentiful current capacity... with a lot of headroom to spare...
contact me offline at acrosound@aol.com if these would interest you.
