It should work, they say it works. It been about 45 years since I had my one and only electronics class in Direct current Theory. Meter movements are a little strange, but I don't remember the particulars. Remember to tie the two end terminals together on the pot if that's what you get. Here's a couple of examples I found on that auction site. The first doesn't have enough wattage, it's only a 1/2 watt, but it has 25 turns from min ti max. With that many turns you don't necessarily have to have a 50 ohm pot you go a little larger say 100 ohm max.

This next one is closer at 1.5 watts, also notice that it could be used for volume control on speakers if you were having problems balancing them. When used on speakers then you can put them inline, because your adding resistance. These are a little pricey, especially since they are coming out of China. It might be due to close tolerance.

Hope that helps, and doesn't confuse.
