Vladimir,
Over the years I have numerous (all-possible) versions of the custom built PSs for my 2x834PT: kinky-regulated, transformer-free, AC regenerated-direct, “special” transformers CL, LC, symmetric AC, symmetric rectification, tube rectification, SS rectification … and God knows what else. I have it currently running with filaments CLcC-filtered connected in parallel, and with B+ separate to the first two and the third stages. The B+ (all 4 of them) are LCLCLCC, all-FRED TO-251 full-wave bridges. The transformer’s primary are powered symmetrically with the cathode followers’ power supply out of it’s AC phase with the power supplies of the first two stages. I may report that the “custom PS” is quite beneficial, however it is shame to say that the original dirt-primitive and very inexpensive PS was sound also very-very good and hardly need any improvements sonically ... unless you are in the domain of a very freaky demands…
