I have identified a 1/4 broken bridge rectifier (RC202) on the control circuit board. There are two of these and I will replace both. Hopefully this will fix the issue

The fix will need to wait till the weekend though ..

Did this fix the issue?

Yes it did. Both rectifiers have been replaced (the broken one and to be sure the other one too). Thanks for asking

Did u ever get the service manual for it? I am looking to buy one. Wondering what outputs they have and what rails this runs off.

I emailed them twice then gave up as they never answered back.
