If you have continuity through the power cord, tube filaments are good. If not, try wiggling tubes in sockets - could be contact problem. REPLACE that selenium rectifier (square finned thing)! A 10 cent 1N4007 will do - band end is +. This will increase voltages, not really a problem though you might have to increase the output tube (35C5) cathode resistor to keep it from running too hot. Or just plug in a 35EH5 instead... it will draw less current.
