Short Ear 302 Plunger Hole Size
« on: July 23, 2020, 05:56:32 PM »
I've got a short ear 302 that has been powder coated and I'm trying to find out what the plunger hole size should be. I measured the current plunger holes with a dial caliper at 0.300 inch diameter.

I read somewhere on the forum that the plunger holes on short ear phones are smaller than a regular 302. 

Info about the 302 short ear plunger hole size would be appreciated.

Thanks,
Gary

I know this does not answer your question but 5302 plungers will fit the small hole 302 sets. The difference is the 5302 plungers are rounded and the 302 ones are almost flat.

Thanks...unfortunately I don't have a 5302 that I could measure.

I measured the plunger holes on a standard 302 and I got 0.370 inch diameter.
The holes in the powder coated 302 short ear are 0.300 (0.070 difference)

The diameter of plunger holes on a 302 short ear or 5302 Or, the diameter of a plunger from either phone would let me know if any powder coating entered my 302 short ear plunger holes

Thanks,
Gary

I found a 5302 in the garage and measured the plungers and holes... the plungers are 0.300 inch diameter and the holes are 0.312 inch diameter.

So, the case is closed (no pun).

Thanks,
Gary
