I would believe this one >>>> Audio-Technica ATM31 | RecordingHacks.com
I have one that I bought back in 1990. Paid $139 for it back then.
Are you operating it off the AA battery or phantom power?

Hi Mark, my amp doesn't have phantom power, so there must be battery power, but I can't see how the battery is accessed. Maybe the battery leaked and glued the thing shut.
I seem to have a memory of changing the battery years ago. I unscrewed every screw and the windscreen end. I know there's a battery in there because I measure about 200mV DC (as from a dead battery) going into the switch circuit board.
Thank you very much,
John
Ahh... Just read the link you provided. Yes, it must be glued shut from a leaky battery. Hope I can salvage this thing. Thanks again.

Yep, got it. What a mess inside! The top half of the battery disintegrated and the bottom half is stuck in there. I have some excavation to do! Thanks.

Problem Solved
It was tedious... but it's done. SUCCESS!
I'll be sure to check the battery a little more often.

I seem to recall that you can wash out battery electrolyte with a solution of Sodium carbonate? Once bone dry a light spray of silicone oil will keep it protected, the stuff you spray on clothes irons.

I'm thinking Dave may have meant Sodium Bicarbonate (baking soda) which could be used on an 'acid' type battery such as in a car. If the AA battery is an 'alkaline' type it takes a bit different approach and actually uses a mild acid to neutralize it. Just go easy to avoid liquid seeping into the electronics of the mic.
