One of my jam mates brought one of these over the other day for me to have a look at because it has gone silent.

On dropping the cover off it I discovered two wires and a resistor floating in the breeze in the preamp stage which need to be returned to their rightful places.

I haven't powered it up but Scott tells me the power light isn't coming on, it is simply in parallel with the heaters so my first thought here is the mains fuse or even the kettle cord.

It's point to point wiring and a thing of beauty inside, but being point to point I suspect it would be a bit too fragile for anything but studio or practice room use.

Edited to add. Google has been no help with this one

Finished up emailing Darrel Hoy today for the required info.

I think I know where the two floating wires and resistor tail go but want it confirmed so I don't let the smoke out

No reply from Darryl but I found a pic of the wiring and took it from there.

It seems to make the right sounds and all of the controls do what they are supposed to so I reckon I am
