I think you're dealing with 75 year old aluminum corrosion.  Acetone won't fix that. I have dealt with the same thing with no luck so far. If you dont have a special pair of exact fit pliers, you're pretty much screwed, unless someone else has a better solution. I do have the knurled rings for sale on ebay, but you'll need to come up with a way cut the old ring off. Very carefull die grinder work to cut the ring only may work. I also have some of the more common recepticales listed. I may have an odd receptacle in the junk box as well. You may only have to weaken the ring in order to remove it. If I have the receptacle, then you can cut through both and replace both.

Good luck.

OK Gents,

I am absolutely stumped: what is the secret to removing the retainer rings on a plug on a FT-233-A single receiver rack? I am finally getting around to replacing J-24 and have soaked it with acetone to disolve the laquer that was applied to keep tge retainer ring in place, but still no joy in getting to even budge. Do I just need more acetone?
