The original horns on my TR-3B work but the sound seems to be a bit muffled. Does anyone have any suggestions as to how to make them a bit louder? Thank you.

The Haynes manual has a complete section on maintenance and adjustment....Pm me with a e-mail address and I can copy and send it to you..

However, it mentions only in passing what I think is most likely: There is a pushrod under the contacts that carries motion from the diaphragm to the contacts. It tends to rust and bind in the hole. It should be snug, but slide easily.
