That sounds to me as though the EHT is low. Could be for a number of reasons...

Are the valves OK? is the line whistle of the correct frequency? Capacitor change - the one to the first grid of the Line Output Valve is a favourite, as is the boost capacitor.

Take out the LOPT and put it somewhere warm for a couple of weeks, to get rid of any moisture. And maybe change the EY51?

Cheers,

Steve P.
