If you will double the current, then two separate HT- windings (wired in "parallel") are necessary.
If you will double the voltage, then wire this two HT- windings in "serial".
The "parallel" option can not be realized with a CT- HT winding :stars:

The use of a CT- HT (for a two way silicon diode rectification) is simply ancient and has no advantage in comparsion to a "modern" bridge rectification.

BTW: I have absolutely no clue why so many US amp builders still use a CT- Powersupply nowadays :what:

The CT for the heater winding is also obsolete, IMO.
A "virtual" CT via 2x 100R or (even better) a good quality 100R Pot is safer. Plus: less manufacturing costs :thumbsup:

Suggestion. Since this is no longer about said Transformer Manufacturer, perhaps a new dedicated topic be started? :what:

A good idea, we could call this new topic:

"The universal Magnetics Corp. Power Transformer"

Because it looks to me that "Magnetics Corporation" is willing (and also able, of course) to build such a transformer for an affordable/ fair price :thumbsup:

so yes

instead of one winding for exemple 350 - 0 - 350, a better option are two separate windings : 350 - 0 and 0 - 350

Digging the new 45/50 watt upgrade Trans. Fired up a bridge rectified 50 watt, and am pleased with the voltage options.
