Did you, or whoever worked on these sets, go through and check the resistors as well as changing the capacitors? It could also be a wiring error caused by misinterpreting the schematic, if it was worked on by the same person, usually distortion of the sort you describe is caused by an open bypass capacitor though a misalignment could also be an issue.
