Greetings to everyone. I purchased this 1936 3 volt tombstone a few years ago and recapped it,replaced a few week tubes and made a battery out of 15 9 volt batteries interconnectec and two D cells to supply the filaments. It always worked ok, but after non use, now all I seem to get is the filaments and a slight speaker buzz. Is it possible that the 9 volt batteries would loose their power from non use for a few years? Any suggestions on how to test the radio power?

Check 9 volt batteries under load. Turn the radio on and measure voltage. Some cheap 9 volt batteries may only hold up a year.

Do you have a power supply?

Batteries in 135 Volt "power pack" power supply are now new, all tubes check fine, volume is very low on only strong am stations with ground and antenna. Do these 9 volt batteries connected provide enough amps to run the B+ on a radio like this? I have a 2 pack of D batteries running the A supply. The radio has a tinny sound and squeals if volume is up all the way also. Any suggestions are appreciated. Thanks,

Measure voltage with the radio operating. Best to check right at tube sockets. Your 2 D cells will be ok if they are in good condition. A radio like this will draw as much as a flashlight so batteries won't last very long.

Squeal could be a sign of weak batteries or a cap open across B+ to B-. Replace C18 and C22.
