69 super Tremolo stand by choke wiring

Can someone tell me exactly how to wire up the screens ht fuse and filercap on the corner of the chassis? Please. Thanks Mark
Do you mean corner of teh circuit board (in the corner above the diode)?
The HT to the board comes via the standby switch out wire, also hooked up to this is the centre tap of the OT, so that is the second connection, the other wire is the wire that takes HT to the choke.
The choke out wire comes back to the board to the same turret as the screens feed wire (usually yellow) and there is also the screens filter cap hooked up to this terminal.
Juice is fed from this turret through the first B+ dropping resistor (sometimes just an 8k2, sometimes two 8k2, sometimes tow 10k in series sometimes one of each). This resistor spans the board to a turret. This next turret has the PI filter cap wire and a bus wire that angles across the board to teh PI plate resistors (82k and 100k) node.
It is all there on the layouts and schems.
