Do I have the wires and everything connected right? Please help. Many thanks. I don't need to connect the 9 pin of the 12AX7, right?
AND most importantly, how do I Ground (yellow green wire) the output section? Should I change the power connector to a FIVE pins one instead of the current Four pins (310 V AC + 13 V AC now)?
The heater wire is better to connect at the bottom, this will avoid some heater noise pick up by the component. The negative of the heater should also be connected to the gound to avoid hum.
