Age old Head Switcher project

Hey, so am just finishing up a bassman build and I am looking into ways to actually use it.

Currently in a small house so can't have too many cabs, but after a bit of searching I found the Aiken schematic for the two head switcher that has the input switch in it (attached to post).

I have only worked off layouts and simple schematics before, so I don't know how these relays all work. Does anyone have a good place to start in turning this into a point - to - point or PCB?

I already have a bunch of 16ohm, 8ohm and 4ohm 100Watt power resistors sitting around and all the rest looks easy to get in terms of parts. And if it comes up, I only have a 2x12 Jcm800 cab so can't do the twin speaker split trick.

Cheers

Relays are simple devices. They're switches. You put voltage across the coil, and the switch engages. You usually have a spdt or a dpdt relay. So the signal goes into the "common" side and there's a normally open (open with no voltage) and normally closed side.

Oh the relays he suggests what you say are the ones to get? and mounting them in a handwired setup?
