GROMMES 221A Mono Tube Power Amplifier, Works & Looks Great
I also show the circuitry underneath. The amp appears to be all original. Physical condition is really good for the age. I plugged it in a variac, slowly turned up to 80v. The amp produced good sound to the connected speaker.

pair of Grommes Model 10PG 6V6 integrated tube amps
These will make a nice rehab project for a novice tube amp enthusiast. They both play but one amp has some scratchiness in the output. Like any 65 year old electrical appliance, these would both benefit from testing and appropriate parts replacement for long term reliability. Since they are 65 years old I’m selling them as “parts or not working”. They are offered for sale in as-is, as-pictured condition for parts, repair or restoration.
