Vintage 1946 Sonora AM Radio Restoration – 08 – Dial Lamp and Speaker

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.

Here is the bulb in the mount with the wiring attached.

And here is where it was connected to the radio
