Howdy
I got the Trafomatic transformers. Nice work, if not aesthetically the best. Simple, unadorned by covers. I'll add pics later.
On the power transformer, I have 3 6.3V heater windings. The GSG board has inputs for 2. Here is my thought:
Wire one winding to the normal left and right terminal blocks on the board. This lets me power the 6A5Gs with DC power, and all is good.
When I install the tube sockets to the board, lift the legs on each socket that are for heaters: Pins 2 & 7 for the 6AX5 and 7 & 8 for the 6SL7. Fly those legs ABOVE the board, and wire them directly to the third heater winding. Insulate where proper to keep the sockets from touching their heater voltage pads on the board. This eliminates cutting traces, and allows me to keep the DC circuits for the power tube heaters.
It would be nice to run the 6SL7 on DC, tho, so maybe I need to look into making a small rectifier for that.
Obviously, the 6AX5GT can't run on DC heaters...
Does this make sense?
Thanks,
Robert
