Dead amp. It never looks right,to me, to use 1/3W anode dropper resistors,
even if high voltage type. Did Marshall stop using HV types, these are
light green body if suggestive of anything?
100K open circuit one to V2p2. 2x seriesed 47K 0.5W will go back in there
and its mate.

Very common for 100k anode load resistors in the preamp stages to fail on
any make or model that uses 12Axx / ECC8x twin triodes ...
