Can someone let me know where I can get hold of the Kelmar Reverse Scan Power Supply Schematic Diagram? I believe Lambda makes the power supplies for them and the model number is SWT30-522. I tried to contact Lambda but to no avail. Can't get to know tha values of the Zeners on the Analog P/S board. viz ZD2 and ZD3.

Best thing is to replace it completely. I usually replace bad scanner supplies with the small C.E. supply which is so inexpensice that it makes repairing older supplies a waste of time and money.

The tax tarrif to India is enough for him to consider to repair the unit.

Alex,
If the problem is TICK, TICK ,TICK turn RV1 down a fraction. Then recal the dolby level.
Or replace the LED.
