Hi everyone. I have a JBL 6230 Ampflier which has a fault which im trying to repair. When powering on the relay clicks and the standby light goes off but only for about three seconds. The light slowly gets brighter after these three seconds.

I got some advice when someone had a look at it, he thought it could be the caps.

I have replaced the two voltage regulators and caps C28 and C30. After this it took slightly longer for the standby light to come back on. I'm now looking at replacing the poly caps C10, C11, C15 and C14 but I feel im looking at the wrong things.
