trimpots at buffer are 100R
easily seen on schematic, first page of thread, each in parallel with 39R

Re: the Handy Addendum PS capacitor board:
Anyone know a suitable NTC that neatly fits into the PCB? CL-60 leads and body too big.

Schurter integrated switch/mains fuse unit inbound as well as 5U/500mm Modushop chassis.
How is best to connect two 16 gauge wires to a single pole of the switch as shown below?
And since I will use two AS-3218 donuts, what is the best method to splice the main / neutral wires back from each channel's fuse to the Handy Addendum NTC PCB's?

isn't that exactly visible from pic? two wires soldered together to switch tab
one wire going from switch to NTC pcb
one wire going from fuse to NTC pcb
make bridges from one section on NTC pcb to other
or make intermediate connection block bolted on base plate, then multiply wires as you wish
which means - prepare (clean) switch tab - preferably apply some flux on it, apply some solder
prepare wire ends - with or without flux, apply solder on wire ends
use wide solder iron tip, say 7mm wide chisel, crank temp to max
bring wires to switch tab, take some solder on solder tip, lean solder tip on wires and tab, as soon solder from tip flow down, liquifying rest, you're done
plasticky housing of switch demands fast and efficient soldering
anyhow, I learned all that after just dozen or two melted various plasticky things
more or less costly
I'm fast learner
Speaking of nuts dug out original 13mm Fiat to affix Ducati caps to floor tray.
squeeze them all as much you can to middle of the base plate, every cm counts
you'll be happy later, doing tweedleefeedly with trimpots
even using just 4cm long mini screwdriver, when space it's tight, it' too tight
bridges - reminder - thermal paste, split washers - or safety nuts
you can squeeze NTC board(s) between Donuts, longitudinally is probably better

Re-mounted CLC as in board as possible. Yes I can see your point about interference with trim pots.
Bridges do have thermal paste and lock washers. NTCs in tandem as you suggest.
