Philco 40-81 Portable
#3

Hi Frank,

This looks like it used a common 67.5/1.5 volt dry battery. Common in those days, anyway. Some guys have built up battery holders in a box to use with radios like this. Fill it with 8 regular 9v transistor batteries for the B+ and a D-cell for the A voltage. The B+ batteries will last quite a long time.

I think there might be a scan of this particular battery case to be found on ARF.

Yes, you need the loop antenna on this set. Otherwise the Det/Osc grid would be left floating. I'm not familiar with the set but it could be sandwiched in the lid or cabinet.

Good luck with it.

-Bill
