Have you checked for signal there while operating all switches and pots through their entire range?
Hi Perry u don't get signal going to driver board what freq do i play in to the rca?
Ok so I should get signal going in to the driver board on the pins where it connects to the main board?
You stated that you have no drive signal. That would mean that the output stage is absolutely dead, no rail-rail oscillation, nothing.
When the output stage is not functioning normally, there is no feedback to the driver board so you will see signal. When the amp is working normally, you will not see any signal into the driver board because it will be cancelled output by the feedback signal.
The input pin is labeled on the attached diagram.

So i can remove driver board and check if all voltages are correct according to schematic then proceed from there?
Hi Perry u followed the signal from rca rite through the pre amp section and found the last op amp doesn't have output only input then i replaced the op amp then it had output through to driver board thanx for the help it does play now drive signal looks good
Yes Perry i fitted lo side and hi side fets and it has a nice big
Square wave on the output drains I even hooked up a speaker and it plays nice
