Love the chrome rails!Although PCB this is a nicely laid out chassisSweet!Great 1979 Amplifier with a few minor issuesOriginal Master volume rather crudely cutGood wiring but pot open circuit in some positionsNew pot installed and ready to go Amplifier had no output. The issue was traced to a poor contact on the speaker impedance selector. The Master Volume ganged pot also needed replacing and it is now it is sounding sweet!
