hi

on one channel of (front) my amp JBL GTO75.4 the volume go down suddenly (half of the power) and then (after 10 - 60) minuets go back to normal and that happen again and again..... I had switched AMP channels inputs and outputs and realized that the problem is in the AMP itself. In edition I had noticed that the problem come more when it's a warm day.

findings:

- no protection and warning lights are blink or on.

please tell me, what can be the problem or which element or component I need to suspect .

Best regards

Ilia
