The power supply in this unit is shut down R607 (.1/1 watt resistor) is open. It uses a I.C 601 (MXO841) for regulation instead of the two VDR's.. I can't find information on this supply but have a request in for a print on this chassis. I was wondering what the common parts are to replace in this supply. The HOT driver transistor and transformer have poor solder which probably took out the supply. thanks for any help, Bruce.
