Welcome to the Phorum!
After you get the paper caps replaced start your troubleshooting by cleaning the AC/Battery switch. Then see if the 117Z3 is lit? The other tubes are hard to see the filaments. Then Check the two dc outputs for the power supply the 80vdc and the 8.5vdc. The 8.5vdc is critical as it power the 1.5v tubes filaments. Too low will cause the local oscillator not to work and to high can burnout filament of a tube or two.
