You need to figure out if the (suspected) bad output tube is really bad or not. Swap them and see if the same tube runs hot or not. At this point I'd either take over the repairs myself or look for another repairman.

Like Bob just suggested, make sure all all paper & electrolytic caps have been replaced along with all out-of-spec resistors. If that hasn't been done or the tubes haven't been tested you really do need a new repairman.
