Welcome to the Phorum!


Replacing all the paper and electrolytic caps and any out of spec resistors is the right way to go. Some folks simply replace the paper caps with modern ones while others gut the old paper one, stuff the modern one in there, seal it with wax or hot glue and put it back in the circuit. It all depends on your preferences. I've done it both ways depending on how I felt about the radio. Aluminum can or copper electrolytics are pretty easy to gut and stuff but putting the new electrolytic under the chassis (after disconnecting the old cap) works also. My 91B electronic restoration thread is here: https://philcoradio.com/phorum/showthrea...#pid119958 and the cabinet is here: https://philcoradio.com/phorum/showthread.php?tid=17643 . Maybe there is something in those that is useful for you.

Those bakelite blocks can easily be stuffed as well. I usually take them completely out to stuff them and then solder them back in. Here's a service tip from our library on doing it without taking them out. https://philcoradio.com/library/index.ph...soldering/ ...and some bakelite block data from the library: https://philcoradio.com/library/index.ph...lock-data/
