MC40s for chassis replacement and complete restoration.

First of the pair to be completely broken down for restoration.

Chassis bottom covers are grit blasted, chem-etched, primed and painted then backed at 105F for 2h.  The pot metal badges are benched to brighten the lettering.

Recapped, power supplies replaced.  All solder pins and tabs desoldered and the OEM leads removed prior to restoration.
