After doing the repairs on my S120 I decided the sound was too tinny. So I changed the .01 cap across the output transformer primary to .02 to cut it down.

CLEG, those washers on the speaker are to eliminate the speaker rattle against the steel cabinet. When I restored my S-120 I used some small rubber grommets in the speaker holes along with the original washers. The original rubber mounts just crumbled on mine when I removed the speaker. As I recall, one grommet wasn’t quite enough to get good isolation, so I just placed another grommet between the speaker grommet and cabinet. Thus far, no rattles no issues.
