pot value help

Sign in to disble this ad
Gday. i just started putting in my new preamp yesterday and when i put the knob on and took it off the volume pot it pulled the hole shaft out preety much. So now that pots stuffed and want to get a new pot asap. I looked at my old preamp to see if it had the same value i needed (50k) but its 500k sadly. Is there any way at all that i could use it as a temporary solution till i get a replacement 50k? Its an active system btw.
Cheers

I would just temporarily skip the pot.

If you need to be able to mute the bass, you can use the 500K pot as a sort of on/off switch.

You can just leave it out and wire whatever was connected to terminals one and two together.

Using a 500K pot with a low impedance signal will mean that for most of the pot's rotation, it will have little effect on the signal.

Once you get down to a certain spot toward the end of the rotation, it's going to abruptly "kick in" and mute.

If you wire the two pots parallel, that's 50K. The only question is how the tapers are going to work.

What are the tapers for each pot?

This is the preamp i have (SE2-A) with the stacked pot. Wiring is apparently quick easy with this as all u do is collect the output, pups, bat, earths ect and then clip the 3 pots to each other. no need to solder then together just clip.

Around these parts it's about $45 per 1/8th.
