Default Need 100K audio-taper quad pot... any ideas?

I'm looking for a 100K, quad-section, audio taper pot, to replace one in a vintage tube amp. Any idea where I can get a decent one, that won't cost a mint? Been looking, but haven't come up with one yet, that didn't require buying 1000 of them...

Thanks!

Regards,
Gordon.

And if that isn't hard enough ...

I also could use a pot, with two 100K sections, and two 1M sections, also audio taper...

Regards,
Gordon.

For the four-section, your best bet is probably a four- or six-deck motorised Alps RK168-series (RK16814 or -16 respectively). There are a couple of reputable sellers of these on ebay. Alps also makes the blue RK27 in a quad version in 100k (RK27114) but whether you'd be able to actually find one for sale is a completey different question.

The second one you describe is probably only available as a customer order, so if you don't need 1 but 1000 then you might be able to get someone to make them for you An alternative would be DIY stepped attenuators where you can solder two different resistor kits on a quad attenuator.

I have 2, both 250k, audio-taper with tap. One pc-mount, one wire. PM me if you could use one. Shafts are 6x25mm. E
