I'm silly enough to ask a silly question - are you sure you put the valves back in the right places? It sounds like your amplifier circuit is working, so you may have switched around a couple of the other valves. I have done that myself.

Make sure that you did not bend a tuning gang plate, or one of the grid caps is not shorting, or broken at the valve top (octals & earlier).

It may be a bad valve socket pin?
