Your finger will act like an aerial for noise into such a high impedance circuit. Much like when you touch the cartridge pins on the cartridge. That in itself doesn't sound like much of a problem.
As for the other noise, that ould be anything; bad valve, noisy resistor or maybe something in the support circuitry/power supply/heatere supply.
