What sort of flux are you using? I hope it is not the paste type flux used for sweat soldering copper pipes. Paste flux contains zinc chloride and/or ammonium chloride, both of which cause corrosion of the wires and electrical leakage under humid conditions.
The only type flux acceptable for antique radio work is rosin, which is also available in activated form for more aggressive cleaning of oxidized surfaces.
