Title: Wire Post by: hywelg on April 11, 2008, 08:59:24 PM 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 Hywel Harris Title: Re: Wire Post by: Pickmaster on April 12, 2008, 02:04:20 PM 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. Title: Re: Wire Post by: hywelg on April 13, 2008, 11:29:29 AM 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?

Capacitace is not a problem - short wire ! 2. absolutly correct ! just find an earth spot on the board.

Its a bit bulky but I think it'll be OK if I support it with tyraps, or route it under the board.
