The most probable causes:
1. The C30.
2. The power transformer leakage.
3. Possibly the Power switch on the Volume control potentiometer.
4. Just measure for shorts between MAINS plug and the chassis, see if the resistance is very low or even in a few kOhms range, still bad.
With good transformer and no C30 whatever short is after the transformer it should not matter, it is decoupled.
