Question about Teac AG-370 Receiver
You've got a fried output transistor or one of the small preamp transistors that feed the output on the left channel. Both of these transistors are after the volumn control so it would have no effect on the buzz. Good luck.

Buzzing is usally AC line noise leaking into an un-shielded cable somewhere or a floating ground. If the AC plug is reversible, try that. Sometimes the buzz is from an attached device. Make sure all audio cables are plugged in tightly at each end and routed away from or at right angles to any power cords and away from other sources of strong magnetic fields like TV's. I've also seen variable track lights induce noise but it's usually minor.
