Vintage Tube Amp

This is a mid 60′s vintage Harmony Tube amp. Cosmetically everything looks okay, but the amp does not work. When it is powered on, the amp just buzzes, but does not register anything plugged into the line inputs. Looks like the power cable was replaced at some point. Please see the schematics and photos of the capacitors/resistors inside.

Excellent condition, tested, works flawlessly, warm amazing sound, please review the pictures. Comes From a smoke and pet free home. Will box it with extra care & attention to details.
