double check work done (cap values and connection points)
look for crossed wires (lead dress of parts on point to point)
check pin continuity of tube sockets to circuits
use sams as a rough guide on resistance (don't get too hung up unless dif are huge, there are lots of caveats on those, read the notes)
a new xtal is a good idea just to eliminate it as an issue, not likely but no real good way to test.
test equipment is the problem, with out a good scope you are hoping to find the problem. So it comes down to guessing based on observation.
Hard to say if the coil diddling could now cause a new problem. If it was mine I would do all the above report back findings and try a new xtal. I prob have one laying around here somewhere but will have to dig around to find it.
for now NO more coil adjusting until at least you do the above. then will prob have to try the procedures laid out for adjustment of the coils that have been adjusted, mainly peaking out the T704.
