Thanks,
The Base is metal and the chip-amps are insulated, no worries always good someone else is looking out for my health and welfare. It barely gets warm- Made mostly from scraps hence the utilitarian look.

Another idea is to sacrifice a cheap donor pot. Open it up and
discard the shaft and other parts and just use the front mounting hardware.

I have to agree. A small sacrifice for a HUGE gain...

Jolly good thinking!

Glad to know that worked. Do post a pic.
I'll try out my own idea soon for a MyRef amp I completed last weekend. ;-)

Another thing I found is that the brass insert from a 60 amp electrical
connector strip makes an excellent 6mm shaft coupler. Cheap
and easy to get anywhere!

Here in the US we have Home Depots and Lowes which are home improvement stores. I get some plastic spacer tubes for large screws / bolts and I use that for my shaft couplers as they are not conductive and isolate the shaft from the pot. Magnetic fields and static electricity are isolated from the pot itself.

But I always had the issue of the bushing in the front panel until quadtech posted that excellent idea.

In Northern California, the Halted.com folks have lots of these for ~ US$1 each, for gangs of six to eight pairs. Surplus stock, but unused as far as I can tell. ( http://www.halted.com/commerce/catal...ACC39330A1A2A6 )

5 channel LM3875 driving into 5 4ohm speakers, plus a 200 watt discrete block that drives the sub.

No input caps at all, film caps directly across the rails.

25-+ volt rails for the LM chips, and -+55 volts for the sub amp.
