I will send you the schematic by email. Your model number is not listed in Collectors Guide to Antique Radios but others around it were made in 1938. You radio was probably also made the same year.

I just got a G99 in really good shape, and I can't seem to find any info.The date of manufacture,schematics etc...I plugged it in and the lights come on and it buzzes out of the speaker,but I can't tune in any stations. This is my first dealings with old radio's and I would like to get it working. I really appreciate any help at all. Thanks Michael Kise
