...and Richard usually supplies paperwork with specs, have you checked the data?
Checked the Transformer, all good, 500v and 30v respectively
Checked the PSU -15 +15 = 30v all good.
Tested both at the same time, I will try 1 at a time.
Yes I have checked the data, correct colour matching for 240v input.
Tested one at a time, same thing. I know a guy with an osciliscope, lets see what we can see there.
