What are the best pots and why?

I haven't looked at it closely for several months but I'm gonna do that tomorrow. What I do know is that it's a dual audio taper. And I believe it is switched because it goes between active/passive. Non-switched would be like a stereo amp volume where both were on at all times and switched is when you choose between one or the other, right?

Now that I remember more about my conversation with Ken and a supporting associate, it's got a tricky mount to the PCB. He sandwiches two boards with a few mm's of clearance between for both PCB's in the bass. I think that's what makes the replacement tricky. I'm not sure that there's a way to separate the boards and get at the bottoms of them without destroying them.

Like I said, I haven't gotten the chance to look at it closely for a while now so I'll try to pop it open tomorrow and with any luck, find a way to replace this pot. Thanks for your reply. :)

BTW, great soldering tutorial earlier! I am also a fan of the Kester "44" 63/37 solder. I like having both braid and a solder sucker around but prefer the sucker for most things.

Yeah, they're probably just afraid of getting blamed if you wreck your board. That's never stopped me. ;) Though I'd be sure I've got the right tools/skills first.

by switching from active to passive, do you mean it's got a push-pull type switch, or just that it fades between them. If it's a fader, I wouldn't really expect them to use audio (log) taper, because it would tend to favour one or the other. Maybe that works out well though, depending on the sound.

Yeah I figured they didn't want to be blamed either. :)

It is a push-pull type switch.

'k, that's a lot trickier to find then. I'm sure you could still find something though.

Might want to see if they'll send you the name of the manufacturer and the part number. Even if they don't want to source them, you may be able to get an exact replacement elsewhere.
 
Alright, finally got to pop the hood and investigate.

Here are the markings from top to bottom:

"CM46007
500KΩ
140-9106"

It's an enclosed type in blue plastic with a metal bottom plate and PCB mounts. I'm gonna try contacting the same associate that I worked with last time and see if I can just get the pot. If you happen to recognize the markings, let me know if there might be an easier alternative (mouser, etc.). Thanks!
 
hmm, no hits. Might be worth assuring him that you're not going to be pestering them with questions, or expecting a fix if you cook it.

I'm sure you can find another push-pull 500k pot though and attach it with some short thin wires, if it came to that. Are you sure it's dual?

sells Alps and some other quality brands. Their minimum is not based on quantity which is VERY cool. I think they have a min $20 order or something like that. I've dealt with them a number of times and they're great.
