Keep the 2x 100R faux CT or the actual CT, just connect it to the elevated DC voltage instead of grounding it.

There´s no Need for Balancing Heaters if using PT with Center Tap !!! it is already balanced!timrobertson100 wrote: ↑Sun Feb 16, 2025 4:33 pm Perhaps a daft question… you don’t use 100R balancing resistors when elevating the heaters?

Some people believe that even if you have a center tap on the heater winding, a better balance can be achieved with two 100-ohm resistors, or even a pot to adjust the balance. You should use either the actual CT or the resistor CT, never both.

Than better use a wirewound Pot,called Humdinger to balance and eliminate Hum........martin manning wrote: ↑Thu Feb 27, 2025 11:47 am Some people believe that even if you have a center tap on the heater winding, a better balance can be achieved with two 100-ohm resistors, or even a pot to adjust the balance.
