Now wire the plate choke on the side nearest the RCA jacks.
Take the remaining 5 3/4" twisted pair, attach and solder one end of the wire to the plate chokes terminal 4.
Route the twisted pair under terminals 24, 29 and 34. Using your DMM to test continuity,
locate the other end of the same wire and attach it to the upper hole of terminal 31. Do not solder this connection.

Attach and solder the second wire of the twisted pair to this plate chokes terminal 5.
Attach but do not solder the other end of the wire to terminal B2.

(you can see the gray 4 ohm wire tied up this pictues)
