Pots! What brands are good?

Thanks Kevin

Thats precisely also what was in the back of my head. Serviceability. And was contemplating on adding a couple of small terminal strips onto the chassis so only the components. In this case the 500k resistor and cap in parallel are soldered onto the terminal strip lugs with wires leading to the pots themselves. In that case it would be a heck of alot easier to unsolder and remove just the components if need be.
