Ampeg M-15 Tube 6L6 Guitar Amp Power Supply Hum Bad news from the first shop Good news from D-lab

Amp came from California. Complaint excessive hum. This unit had just been serviced at a shop in another state (KY). Yep, a victim of the King Kobbler. Terrible work. Made the initial problem worse. Plus, the tech was a chain smoker, so the amp is now contaminated with his exhaust! Unfortunately, the owner had to ship it again for proper repair. He was considering me first, wish that had been the case.
