Wiring up a boothill Amps 5F1 and Dave sent three, three-terminal jacks. On the speaker jack How should I wire the "switch" terminal? I would assume grounding it would cause more damage should the speaker come unplugged sending the positive from the OT directly to ground. Or should I put a 4 ohm resistor in there to ground as protection? Also I'm using a classic tone 40-18030 OT, The Red wire common is sent to the positive side of the first filter cap, and the blue to pin 3 of the 6v6, correct? It seems strange to me to have a common at +340V. I also used the Blue 8Kohm primary, is this Ok with the 4ohm output? Thanks in advance for your help. I'll post pics before firing it up.
