Sounds like a loose connection, check the easy stuff like the AC plug and fuse cap (if there is one). If the tube filament circuit provides filament power in series to any of the tubes, you could lose both channels due to a bad connection at a tube socket or even a tube, but it sounds like you substituted all of the tubes.

Try touching all of the above to see if you can recreate the problem at will. I wouldn't be too concerned about powering it up, tubes and associated circuits are not like solid state where a failed component tends to damage others.

The watch the tube glow suggestion was a good one, if it is something like power plug or fuse you should see the filaments go out and come back. Watching in the dark is good way to do this.
