Hello Chuck,

An AC meter? Does it have an internal rectifier?

I thought it might be a tuning meter for substitution or alignment purposes.

It will be very interesting to see this thing.

Although not made by Philco, here is another somewhat related item I just picked up. The resistance line cord is "toast" so it can't be plugged in.

In this case I'm considering modifying it with an internal transformer so that it actually works and is safe to use. But then it won't be original anymore.

Unfortunately, I have no schematic, so when you get it you'll have to generate one for us.

Can't be a whole lotta circuitry in there....
