Default Re: AVO Model 7 Restoration

Well, if nothing else, the current situation is providing a fair bit of
spare time.
Finally got fed up with looking at the Model 7 sitting there waiting to be finished.

Had to repair two open circuit Windings in addition to the prevoius issues, so had to give in and replace
with Modern Resistors! Hate doing that, but there is no other way really these days.

Got the Two Pack Resin out and re-molded both Dome Terminal Covers. Fortunately the Brass Parts were still present.
Also took the opportunity to use left over Resin to make a small repair to the Chip on the Front Panel.

Tested AC & DC Volts, Amps and Ohms.
All pretty much now within Spec.
This Meter is now 74 and a Half Years old.

Photos show the before and after for the 36 Range and Model 7 which I
bought together as spares in 2018.
Now both restored and working.

Will they ever get used in Anger?
For sure they will !
