Hi Stalker,
on some Hasimoto circuit I saw a SE output used for push-pull. The four primaries had a tap such that it gives two sections on both sides. The SE impedance is 3k5; the Raa wil then also be the same, 3k5.
Then what is the impedance of the "tap"? This is 2k5, as this is the 3k5 divided by 1,4 [2 square root].
What I see in your example does not fit this logic!

In the described circuit, 2x 2k5 is admissible for a 300B for instance.

SPU --> tube MC/RIAA;
Pass buffer -->300B SE + DN2540 CCS/Buffer; --> 165GMF in TQWT; working on a HYPEXed sub.
