Hi,
Just to make sure I understand: I have a 6.3V AC supply with CT and a 5V AC supply with CT (one for each 5AR4/GZ34 in a two-channel Mark III amp).
What's the preferred way of referencing the CT? The MK III schematic shows a .02 cap connected between CT and ground (my star ground bus in this case).
In other circuits, I've seen resistors used: one from each side of the supply connected together on the grounded side. This method seems to be used when a CT isn't available.
Your thoughts would be appreciated. Thanks,
Chris
