LM317T Voltage Regulator with Pass Transistor

Pretty much repairing a Kenwood audio/video Receiver VR-606, at first bought it thinking it was bad voltage regulator, turn out to test good, so their was no reason for the display not to work and ended up remembering see a video from "uxwbill" on one of his "table repairs" and him having the same problem and it was the same problem, cracked solder joints around the deplay driver IC. Will resolder it and test further and clean receiver.

Help! I've been bitten by the vintage stereo equipment collecting bug...here is another 1980s Technics stereo receiver in good working condition. From the looks of it, this was a highly basic model. It offers only 25 watts per channel of output power into an eight ohm load, tuner, tape play/record and turntable inputs. There is no AUX input, although the tape playback input can be used as such. I need to clean up the tuner memory backup battery holder. There is also a capacitor on the main board that looks to have been a little warm, as it was leaned up against a very hot voltage regulator. I may replace it. I also removed a ton of dust from the inside.
