WTB: Fluke 21/23/70/73/75/77 series 683052 (AP75) analog processor

[shakalnokturn]

Trying to repair a Fluke 77 III, if no luck on sourcing cheap IC I'll also consider selling multimeter parts or for parts.
PCB is corroded by battery leakage, LCD works but has light damage to back polariser/reflector on LHS, function switch, resistor network and U2 LCD IC are good, DMM case and protective holder are in decent condition.
Make offers either way...
