Ohh no, " 20 Ohms or less" IS my thing!! That was the very first thing my audio mentor, Robert Fulton, taught me in 1982 about power supplies for tube audio..." 20 Ohms or less if you can find it ".1 HY at 10-20 ohms, not too large and heavy, is cool and nice.
My favorite off the shelf choke is no more, the Stancor C-2708. Never had it buzz, rated 320 mHY and it measures 490 mHY on average. Actually, I never really use Triads, as I have NLA Stancors.
The 320 mHY Triads I have measure about 340 mHY BTW. The Hammond 159ZBs were a dissapointment to me. Rated 320 mHY, out of four samples, they measure about 225 - 245 mHY !!
In all instances, I do use L1/C1/L2/C2. C1 may be about 30 uF, C2 about 50 uF. FUN to hear !!
