Firm that will supply one-off pots to order.

[Yorkie]

I've known of the existence of OMEG - a UK firm who will make any pot to your specification, but has an MOQ of ten pots, but have just learnt of the existence of a firm in Wales called Blore-Edwards that will also supply pots to your specification. I've phoned them for a chat and they seem very friend'y and helpful. (I spoke to Brett). They're happy to deal with retail customers and accept paypal. As restorers often seem to want to know where to get 500k log pots with a doubl- pole switch for sets such as the DAC90A and DAC10 ( Oh dear - I'll have wash my mouth out now with soapy water for using swear words!), I asked if they coulsd supply them. Yes, for one off they're £6.22 + P&P plus VAT. You can ask for 6mm shafts or 1/4" in Delrin or brass, in two bush lengths.

They also do double or triple gang pots.

If anyone is stuck for a 'special' pot it might be worth getting in touch with them. This is from their website:

• Wide range of resistance values
• Available multi-ganged (also available fitted with AR MAINS switch)
• Customisable across the whole range
• Customisable from resistance value, to termination type, to spindle lengths, diameters, flats and slots
• Hard-working and reliable
• All custom and standard potentiometers are assembled to meet full performance specifications

How to design your own customised 45 Potentiometer
• Browse our detailed specifications on each type (listed below)
• Ensure that all relevant parameters (type, value, etc) are identified
• Indicate any customisation you require (multi-gang, mains switch, spindle type, termination type)
• Note that we will try to accommodate any non-standard feature such as bushing type, spindle variation etc

If anyone is stuck for a particular pot it might be worth getting a quote from them:

What's more, the also do rotary wafer switches up to seven poles and 21 ways. Hmm, that could be a good way to make a replacement 'pot' vor the AVO valve tester (is it the VCM 160?), which is wirewound and tries to emulate a log pot by using three different gauges of resitence wire, one of which seems incapable of carrying the current so burns out in the routine manner. I'd have thought that 21 steps using 2 Watt metal film resistors would provide a smooth enough log law plot to suffice as a replacement for an irreplaceable poorly-designed wire-wound, prone -to-failure relic from a bygone age. Just thinking out loud really - it's not an ishoo' for me.
(I know that some time ago Colin ('Retired') went to a great deal of effort to skillfully hand craft such a replacement wirewound pot, but was thwarted in the end due to not being able to get resistance wire in small quantities).

Hope that might interest someone.

Thanks David,

I will be contacting them for a replacement volume control for the Roberts R900 if they can do the tap. If anyone else is interested, we might be able to do a volume order too.

For 'standard' value pots then Phil Taylor of the BVWS normally has some. 500k, 1M, log/lin, with or without switch.

Thanks for the link David.

Thanks! I've known about them for some time, but assumed that there would be Minimum Order Quantities.

Have used their switches in the 'day job' - very good quality, but expensive.

The potentiometer cost is a pleasant surprise!
