Default Simple SE 1 dead speaker & front tube getting very hot very quickly

Hi, I fired up my amp this morning to find no audio in the left hand channel

I have re-flowed all the sockets which has caused dry/poor solder joints in the past to no avail.
All the heaters are on and working, the front tube does get very hot due to it not doing any work

what parts and where should I test?
Is it possible for the MOSFET to have failed and what would the symptoms of that be?

solved, turned out that a leg had disconnected itself as the joint was re-flowed

its always the simple things, but its all good now.
