Question
robm
Picked up a Stars Phoenix a few weeks ago, and due to their stupid design (combined with my stupidity), i plugged the lower plug that brings in all the transformer voltages one pin off. It appears to have only affected the high voltage section with no displays working - there is 2V at the 170V test point - all other test points appear OK.
See pic in next post, but i have replaced TR1,2 and 3 and am thinking i shoudl replace SCR1 next - i have a Zac Clown, and get 170VDC out of the top leg on it, whereas on the Stars, it is only 3V.
Am i on the right track, or are there any other components i should look at replacing as well?
