I had previously discovered that pressing on the main PC board could induce the problem, further isolated it by applying pressure to the outpur amplifier modules on the heat sink and ultimately traced it to cold solder joints underneath the PC board where the output amp connects.
To aboind having to remove the sub assembly from the chassis, I used a DREML mini angle grinder to cut away the botton of the chassis, just under the amplifier connections, giving access to them and more in=mportantly, making it possible to test for success which is not possible when the power ams sub assembly is removed. I have photo's of the underside of the PC board if they are needed.
