Hello, I got this Philco 611 for free. I did not realize it was an AC/DC set until I started to look at it wondering where the power transformer was. Guess what there isn't one you big dummy. Checked the tubes and found the 6 volt ones had open filaments so what happened there? The 43 and 25Z5 are good. I thought about just using this radio for parts as the cabinet is pretty beat up. I want to see if it plays so I tacked in replacement ecaps cutting out the old ones and replaced the dead tubes. Bought it up slowly. There is not a peep out of it. All parts of the speaker are good. I started to check voltages and noted at most 12 volts from chassis to what ever. So I tried cathode to plate on 25Z5 and get about 117 volts. So this makes me wonder how do I read the voltages on the other tubes as in where do I connect the negative probe?  

Yeah I know its a waste of time to troubleshoot a radio with original caps. I just want experiment a bit. At least get the audio amp doing something.
