[Heathkit] HDP 21/Shure 638 Microphone disassembly

[Jim Shorney]

Do you mean E-V 638? I've never had one of these apart, but I would suggest
looking under the nameplate on the rear of the mic. There may be a hidden screw
holding the head together.

I want to restore and clean up the mic element screen on one of these, but have not been successful in getting the head cap loose.  So far, I have only attempted this using brute hand strength and without tools.  I assume it "simply" screws off?  Perhaps it is a press fit?  I do have a Sears adjustable rubber belt tool at hand, but have not tried it.  (I also have pipe wrenches and a large vise!)
