audio taper pot needed

[Nunya Bizness]

I need a replacement dual-ganged 500K audio taper pot for my old Pioneer SX
828 receiver. If I was a dreamer I would ask for that with center-taps too!
I have had no luck with certified dealers and E-bay can provide another
parts set, which I am reluctant to ship across the country. Has anybody
tried to substitute a linear taper for an audio taper, is it a bad idea?
Thanks, Jake.

Yes, it is a bad idea, unless you want all the control in the first
could percent of the pot. Your hearing is logarithmic so the control
has to match.

Check places like Mouser for stock controls that you may be able to
adapt. Some places sell shaft couplers to allow you to saw off the old
shaft and couple it to a new pot to make it look like it was the
original part after the unit was re-assembled.

Prolly a bad idea!!

or use a lin pot of same value with a 'law faking' resistor, about
1/10 of the pot value, connected to slider and earthy end. works (ish)
and gets you out of trouble

Thanks to the group for the advice and the links, I will make the purchase
and stay away from the linear pot.

Is it Physically damaged? If not, i would try some caig labs products on
it to revive it. D5 or better yet, pro gold.

Yes, the damage is severe, grating-scraping ( unamplified ). I will replace
with similar pot, just won't have a center-tap for the loudness feature.
Thanks all,
