Zenith MJ1035 volume pot question

[electroking]

If a circuit has a source impedance such that it wants to see a 2,000,000 ohm load,
and you load with anything below 200,000, you have essenially shorted the source,
meaning that the output voltage is now about 10% of what it should be. With 1000
ohms, it would be much worse. A short-circuit need not be exactly 0 ohms, it
just needs to be much smaller than the optimum load impedance.

I will look for a correct pot for you, and as you said if anyone has ideas, please
come forward with them. Regards.
