Grommes
Grommes-Precision of Chicago and later Franklin Park, Illinois, is one of the less documented American makers, and the original magazine's posts are a useful record. The Little Jewel was its famous small kit amplifier, here in a mono version with 6V6GTA output tubes and its original gold faceplate. The G-50 is a serviced power amplifier with Tung-Sol 6550s, and the S-20 is a late-1970s mono amplifier found new in its box, with 6BQ5 (EL84) output tubes.
Little Jewel kits taught a lot of people to solder, so many surviving examples were assembled at home. Check the work before you buy, and confirm the exact model number on the chassis, since the line ran through several versions.
The company history page tells the founding story as Grommes itself told it.
