I have bought nearly all components, but I can't find LM6171 and Alps 10k potentiometer. I can only find Alps 50k potentiometer.

My question is:
What other Op amp can replace LM6171 and can I replace the 50k Ohm potentiometer with the 10k Ohm one?



Thanks for your attention.

Not sure where you are located, but...

You can buy Alps 10K Black Beauty potentiometers from Michael Percy Audio, at least according to his catalog you can. These are not exactly the same as the one Jan uses in the Corda, but they are probably similar. You could probably just use the 50k one, but I would just ask Jan, he can surely tell you if he recommends changing any values based on a 50k pot.

I've seen the LM6171 at digikey. The part number is LM6171BIN-ND. Pretty inexpensive at $2.83 a piece.
