Maybe, but it doesn't explain why his receive works with the amp off, but still connected.

Could be a bad switching transistor if it is a solid state amp. I had dirty contact's once and it did the same thing. I would do as 833 said. Clean the contact's even if they do not look like they are dirty. 833 is always right. |
