Dead as a doornail
#1

    Just finished recapping this B 1750 Radio (with phonograph) - it's from 1954.    Put tubes in it, plugged in and ZIPPO - not a thing.  It's completely lifeless. None of the tubes glow, nothing gets warm, nothing lights up, no buzzing or humming -  almost as if I didn't plug it in.   I really took the time and did a good job on the caps - make sure all connections were tight, used insulation on all exposed cap wires, and checked my work. 
    I did not replace the power cord yet - but there is continuity between the prongs on the plug and where it connects into a buss terminal  - so I believe the power cord is NOT shorted or severed inside.  
     All tubes check out good and I even have another set of them - which I tried as well -  same thing - completely dead.  The on/off pot seem to be  solid, not loose or anything, but not sure how I would go about checking to see if it's good as there are like 3 different rows of terminals on it.  
      The transformer you see on top of it in the photo is an audio transformer - so I believe even if that were bad, I'd still get some tubes lighting up, if nothing else. 
       I did not turn it on before I recapped it so I don't know if it worked before I recapped it -  but I was the first one in there since 1954 - it was completely untouched and unrestored.   All wires seem to be attached to wherever it is they are soldered to - although I will look more closely later.
       Any suggestions as to where to start looking for a problem that would cause this thing to have ZERO power when switched on?  Thanks    [Image: http://philcoradio.com/phorum/images/smi...on_sad.gif]
