I'm intending moving the two trimmers to the rear panel. Do I need to worry what sort  of wire I use? Obviously it needs to be large enough guage, but any special type?

Thanks

Yes, you need a TWO core shielded (thin microphone) lead.
Shield (ground) must be soldered ON THE circuit board’s ground spot NOT to the chaise’s ground.

I thought that would be sensible, but Nick suggested it might not be necessary, to try it and see. Well, I won't want to revisit this after its all housed in a cab so I'm going to go with screened cables to be on the safe side.

Any idea what conductor area I'll need for these? And I'm assuming the lower the capacitance the better?

Any i presume the earth side of the pot won't need a screened cable, but that it must be earthed back at the board and not at the chassis?

Thanks

1. Capacitace is not a problem - short wire !

2. absolutly correct ! just find an earth spot on the board.

Decided to use some George L's .155 that I've already got. Its a bit bulky but I think it'll be OK if I support it with tyraps, or route it under the board.
