It didn't go so well. Smoked one, so I replaced those with some Fender 50K pots. That's what I got in there right now. Good quality, but not a true linear taper. Right around where I need them to be, they get twitchier than a millipede with restless leg syndrome.
That's an even dozen pots so far if anyone's keeping count.
So ... to make a long story longer ... I found some "precision" pots at that auction site that looked like they'd fit the bill. 10:1 ratio, so I figure those should give me lots of range to play with when dialing the bias in. Once again Hong Kong source, but I usually have pretty good luck with their stuff. Took forever to get here from China - blame it on the monsoons. Always figure on delays this time of the year.
Anyway ... they got here today, and I gotta say, they look and feel like some nice pots.
But wait, all you pot people are saying ... those look a LOT like Bourns? You know, the ones Mouser sells for $15 each ... without the knobs?
Uh yup ...
