Sony kv1722

Well, I'm also helping out jstout with this Sony. Well I think I had a disaster. I found the transformer to be open on the primary side. So I decided to remove the transformer, and see if I could find a replacement. Then I put the circuit boards back in place, and darned, SMOKE!. I must have shorted something on the power supply board. The 2 SG613 are not shorted, but I burnt out R608. It has been replaced before, and the color code is burnt too bad to read. It seem to connect to SG609, which is a SCR type thing. Like was said one mishap and puff it's gone. Well any info, or otherwise might have to junk set.
