High voltage is too low - any ideas?

I have a 1962 Philips where the HV has dropped. The voltage is too low to make the filement of the HV rectifier glow, so i doesn´t get a picture. I tested it with a rectifying diode instead of the tube, and that gave a small (about 50-60% of the screen), blurry picture, so i know the rest of the set is working. I have replaced all the tubes and el. lytics on the Horizontal/Vertical and line output stages and carefully checked all soldering joints, but it doesn´t make any difference. When i turn it on i only get sound and the "whistling" sound from the horizontal output. The smoothening capacitors have dried out and lost most of their capacitance, but i guess it should give a picture anyway?
