F5 low output

[esprit]

Hello
Following the decommission and reassembly of my system (for decorating, the room that is) one of my F5 mono's is now very low on audio output. The power supply and bias is functioning satisfactory, however the offset seams slow to respond to pot inputs.

Any suggestions

Best Regards
James

Check grounding on that channel

swap inputs and see if the low has swapped as well.

F5 Low output

Hello

The fault has been isolated to a single box/ pcb.
All grounding path's checked, including the 10 ohm resistor's to ground.
The pcb / components, show no signs of stress ie burning/overheat and all pcb tracks look intact.

I believe I am correct by saying that, the symptoms are being seen at both of the mosfet's.
