Re: Tek 485 - Intensity at Max, Cannot Adjust Down



It smells like a DC restorer problem. The best test is to replace the diodes unless you have facilities to test the leakage at high voltage, the circuit is very sensible to diode leakage and a DMM test usually is not enough. Since anyway you have to remove them, it is safer to replace them. Another suspects are the restorer's capacitors.
