Does anyone have a Kenwood KR-2300 receiver, could help me to find replacement/equivalent for the power transformer. I believe it's toasted, since I check the voltage on the secondary and got no voltages reading. I couldn't find any service manual except the attached schematic. The primary have the Red&White. The secondary have 2 reds, 2blues and 1black wire. The marking say L05-0029-05 and 7S3Z6 and nothing else. Greatly appreciated.
