I acquired a philco 40-185 recently in original condition.  The previous owner said he plugged it in and the light came on but it hummed.  I brought it home and took the chassis out.  (This is my second restoration.)  

nyway, I replaced all the old paper caps and the two electrolytics (and a few resistors that tested badly).   I added a fast blow inline fuse.  I replaced the AC line with a modern cord.  I rebuilt the bakelite block with two .01 mfd safety caps.

I have it all put back together and tested it with a dim bulb tester, but no dial lamp and no light at all on the “dim bulb”.  I can confirm there is 120v coming in the main (hot) line which enters the chassis, goes across the fuse then to the bakelite block, then to the on-off switch and back to the AC transformer.  There is 120v all the way to the transformer line on the on-off switch.  The neutral goes directly to a bakelite block.  No tubes are glowing.  No dial light.

Now, I’m stuck.  What should I look for next to determine the problem?
