OR80 amp ohms???

Post by nlimbaugh » Sat Nov 23, 2019 11:54 pm

So, I've been using my OR for over 20 years and I used to post a bit here..... Anyway, I just saw someone mention OR80's from the 70's having the wrong impedence listed. Someone said the 16ohms is really 8? I've been kinda meticulous about using correct ohms etc and I never knew this. Is there any truth to this. My 4 ohms mark has been overmarked, I have an 8 and a 16 ohms selector. I think my OR is a 1976 or 1974.... I dunno. I've kept it in top shape.

Actually, the only way to know for sure is to visually inspect the wiring from within...

What would I be looking for? I sent it out about 9 years ago to a guy very familiar with OR to replace my caps. He mentioned that the fast fuse was actually 1/2 amp and not 1. Do you figure he would have spotted something off with my ohms selector , or, is it something really obscure that one would overlook? I had never heard of the ohms on the selector being off before I read someone's post but I haven't been on the forum for a number of years.

You would totally overlook it. It's fairly easy to stick in the voltage selector for 4 ohms and see if the pin is actually wired. In mine, it was just turned so 8 and 16 were wired...
