A few years ago I refurbed a 40-180 for a friend. Physically it was mint. I tested/replaced bad tubes and recapped where necessary. the radio worked fine but I was really disappointed in the audio response. For a radio with a large speaker it sounded like a typical AA5 table radio with a 4 inch speaker.
SO I added feedback to improve the low end response as well as some power supply mods. Well worth the effort IMO. This may also apply to other sets.
