My tssa v2 to V8 is a lot more complex to keep it all running as you already had figured out. But Then it is possible to run it In class AB without sacrisfying Performance

If it's going to operate at 2A idle current the heatsink cannot hold that much heat generated , this is the reason why I avoided Class A but I'd like to try my hands on point to point wiring but not on a Class A

Thanks Sonnya

Hi
Symmetrical topology you are exploring is VFA which is not preferred in this thread. TSSA is CFA in CF output's configuration ie. voltage driven CCS. I would kindly ask if you can please proceed to find help in some other threads. Thanks for understanding.
Regards, L.C.

May I suggest #7 - here - Slewmaster - CFA vs. VFA "Rumble"

You might also want to reference - Leach Amp Plans - Part 1 "leachamp" = #7 (spooky) ....
