If there is no sound (not even hum?) or raster then you probably have a low voltage power supply problem, (low voltage in this case means something around 400 volts so be careful) Does this set have a 5U4 tube, that one tube with the shoulders looks like one. Anyway, if it does, that will be the low voltage rectifier. check to see if it's lighting, a shorted or leaky filter cap can blow the heaters right out on that tube or cause the plates to glow orange. You can also check the voltage at the filter cap attached to the 5U4, should be several hundred volts, if not the cap or tube may be bad. Even if you get the LV power supply working correctly the set will probably need the paper caps replaced to make the rest of it function right
