Some time back I worked with a 155 Mhz Sinclair Duplexer in the 2M band. I could not get the notches to tune properly, so I added a Type N elbow in one leg of the circuit. This made the coaxial jumper about 1" longer (bungee coax) and solved a problem.
I would be much surprised if cables were an issue, unless they had been messed with extensively or modified. Usually a duplexer just sits there and works for years and years, and the cables are usually not moved very much, unless someone monkeys with things.
