Hi Nick,

will heat to remove the tar but is it recommended to do this with the metal-cased condensers? 

They have a cardboard liner inside so sometimes you can just put the innards out after sniping the gnd wire. Or the tar will glue the cardboard to the tin.

Cord and plug

The last cloth cord I got was from amazom. I think it was listed in the lamp/lighting section. 7' long and abt $7 has a modern polarize plug. You can easily clip it off. The old skool plugs are commonly referred to as acorn plugs. As a side note Philco used cloth cords till '37.

Cleaning tuning dial 

I would use Qtips and odorless mineral spirits. Never use water or soap&water. This will remove the print from the dial.

I’m hoping the shadow meter works

Generally the big issue with the sm is the internal coil being open. Easy to measure the coil resistance which should be abt 1k or so. If it's 100k you'll need some 40G magnet wire a 3" 1/4 20 bolt and nut. Oh some sets have a carbon resistor in parallel w/the coil so that needs to be out of the circuit to get an accurate reading. Said resistor is on the chassis not inside the meter housing.
