Well I went through this sweep generator and the sweep oscillator section is being problematic. With my frequency counter attached to the output I can see it is way off from the dial setting and isn’t stable at all. It jumps around in frequency and doesn’t settle down. There’s not a whole lot to the oscillator, all resistors are good and the few caps are disc ceramic types. I have changed them anyway but still the same. It uses what Heath says is a saturable reactor or increductor along with the tuning cap. The increductor is coated in tar which has cracked and flaked off in spots. I have one hope left and that is to get a new 6BQ7 oscillator tube and try that. If it’s that increductor then this will be only good as a door stop!
