Vintage 1946 SONORA AM RADIO RESTO-MOD PROJECT
Dial Lamp and speaker:
The original Dial Lamp and socket was completely missing from the radio so I had to find replacements. The Schematic told me that the bulb was a standard No 47 bulb which is a very common bulb. It is a 6.3 volt bayonet type miniature lamp and can be found at a number of different places. After a bit of research, I found the bulb and bayonet type socket for the bulb mount at a local electronics surplus supply business. I wired the bulb socket to the locations marked on the schematic and inserted a new bulb into the socket. I also soldered the speaker back into place and mounted the speaker back to the chassis.
