I see why at least one of the 6 volt tubes burned out. While the input voltage is at 105 volts the 6 volt tubes are at 6.2 volts and the 25 volt tubes are at 21 volts. The tubes are all .3 amps. The canned ohm is reading pretty much spot on so why are the 6 volt tubes getting so much voltage?
Also when I do DC checks I am getting over 80 volts no matter where I probe in the radio even on the volume control connections. I'm using the AC line where the one wire is not connected to the 25Z5 tube for the negative point. Why is this? Have I misunderstood what Mike said earlier? Frankly I don't get this radio. I've started on this so now I want to see it working.
