Horn adjustment

Post by Unprr » Mon Oct 20, 2025 10:18 am

I have a horn manufactured by E A Laboratory and need help with the sound adjustment.
Per the photos attached. My adjustment screw looks to have been replaced and a lock nut put in its place.
1. Is this an after market addition.
2. Any ideas how to adjust.

The horn has worked perfectly for years.

I think you had four posts of advice on your last post. Looked like good advice.

EA were one of the suppliers for A model horns. Perhaps an A model owner could help
