Look carefully for burned resistors in the power supply, you will probably be able to see them.
It’s quite possible that the replacement valves are ok and it’s another fault caused the problem, it happens, just moving the chassis in a vintage TV can break insulation on wires etc.
A careful check for burnt items hopefully will spot what part as burned, then you need to trace out why.

I've looked and nothing is visibly burned, as it is now with the old valves back in the audio section is still working perfectly. The 805s are in horizontal and vert sync and I'm willing to bet they can cause stress. I doubt very much that just unplugging two valves and plugging two new ones in has made a wire come loose because the chassis has been in the same position for weeks.
I'm not touching this tv again for another few days. I need a holiday from it.
