[Music in a bottle]

Steve? Does the heater circuit control all the tubes or are the heating elements controled individually? I have other tubes that I could plug in... I believe I have two extra of each. I need to try it out when it's dark out I guess. So they should at the very least, be visable then? It is as I said, that it was making the hum instantly when the switch was snapped on. We recently purchased a totally restored 1937 Zenith tombstone...........Yeah, I know.......$$$$$$............ and I all of the sudden want to get the cheap old Philco 70 going now!
