I am new to the forum and radio restoration in general.
I have a Philco 39-85 121 that requires the A-B battery pack.
It still has the 4 prong connector.
I built an A battery pack out of 6 D-cells wired in parallel.
I may have somehow messed this up because the pack voltage read 3V.
The A pack was connected to the two prongs that were closest together.
The B pack I built out of 10 9V batteries wired in series. Their combined voltage read 89V.
The B pack was connected to the two prongs that were farther apart.

The tubes powered up yesterday, but there was no sound coming from the speaker. I checked the speaker and it is good.
Anyone have any suggestions? Did I possibly connect the packs incorrectly?

I tried to power up the radio today, but the tubes would not power up.
Any advice would be helpful. Thanks.
