I'm trying to fix a pair of 40 year old RTR180-D floorstanding speakers, They've got a simple crossover with a couple of capacitors and 3 resistors in each side, and a 16ohm wire wound pot. Which is dead. Well, I reckon it's a pot (a dead one), because it has a single wiper arm. L-Pads have a second arm at 180o .Apparently. This is so it presents a constant impedence, or resistance or something. Apparently, according to Google. I'm not really a "wires" guy.
16ohm pots are kind of hard to find nowadays, but L-Pads are available in all manner of ohmerage. Can I replace the pot with an L-Pad?
The rest of the bits were easy to find and buy.
I've asked exactly the same question over on Audiokarma forums.The silence has been deafening, but at least I didn't get the DASFFS stuff.
Anyway, does anyone have a clue? I've tried opening it up to clean it which is how I know how many wiper arms it has and at what angular spacing they're at.
In abscence of any real knowledge, I'll gladly accept semi humourous smart arsed replies that make me giggle.
Cheers!
