When I switched the radio on yesterday the HT was low at 140V. After dinner I measured the HT again. It was 140V for a few minutes then it rose to 210V.

This evening the HT is still low so I'll comb through the power supply tomorrow.

EDIT: How would I know which mains tapping the (dropper?) resistor is set to?
