Cool, I'll see if I can get the specs off the cap. There is a slight hum, but it is playing nicely. Needs some more switch cleaning as the sound is breaking up and goes in an out until I touch the source knob. Playing my iPod through the tape in. This thing is cool! Looks like a label fell off the back so I have no idea what model it is. I assume that because there are 2 7189a output tubes, it is SET?
