I have a TX3 that say unused for too long.
The battery contact have all been eaten away.
I can't locate a new battery carrier for the meter, assuming the contacts are part of the assembly..
Does anyone have any ideas how I can repair this damage?
As far as I know the actual plastic part of the carrier is ok, but all of the metal battery contacts have corroded away.

Any thoughts or leads to parts appreciated.

I still use the older 70s-80s equipment, 475 scopes, TM500 series plugins. Too old to change!.
