Noticed most Setton posts are 20 years old.
I'm repairing a Setton RS-660 for a friend. He did the thyristor update and it doesn't work anymore. I plugged it into a DBT with 70watt bulb and it stays bright. Serious short. One of the 15000uf PS caps gets warm in a short time. Brand new Vishey caps. All voltages are low <50%.
Looking for any RS-660 owners who have experienced this problem.
