[AMRadio] Any deep pockets out there?

I have awful luck with any games of chance, so I am a bit fearful of buying a set of these:

I need a set for a BC191. Has anybody tried these out or know of anybody who has?  At 4 for $220, if they worked I could thumb my nose at those trying to sell them for hundreds each, just for and unknown vintage, NOS one.
