[Mr. Radio-Man]

Hello RodB,

I found this diagram for the OPT
I mainly am just wondering where exactly I put the wires cause I don't want to mess it up in any way.
I am still new to everything and even after I read your comment I still have no idea how to do what you are wanting me to do lol.
I think I have an idea on what wires do where.
Red wire connects to pin 4 on the 6F6 tube (Screen Grid/B+ rail)
and the Blue wire connects to pin 3 on the 6F6 (Plate)
and the brown wire is unused.

Secondary (speaker)/

Yellow goes to the small red wire coming out of the speaker cone
and the black wire goes to the small blue wire going into the field coil housing (hum-bucking coil)

I just want to make sure that this is how its going to need to be wired up.
