My second 7503, which I thought was completely dead, is actually showing signs of life.? It has a P11 CRT, which is fairly dim at max intensity, and activity can only be seen with the beam finder pulled out.? Mechanically, the scope looks like it had a bad day at some point in it's life...
Are the schematics anywhere online for this scope?? All the manuals I've found so far are copies of the 96 page version, which is missing everything after the description of the readout system.
