Daytona USA Arcade Twin suddenly goes crazy

[Bluechen]

Hello my Daytona USA Arcade Twin suddenly goes crazy.
The right one is suddenly extremely loud, I can not make him quieter on the volume control. Maximum volume all the time.


Someone has an idea what this can be ?


Thanks

It's likely either the volume pot or the amp.

Measure the volume pot to see if the resistance is changing when you rotate it.

If your pot is OK, then swap the amp from the other cab.
