    here is the bottom of the set.

from my research the bare metal bar is what i "think" supposed to be the DC Buss.
right now i have no voltage on this bar.

i have also read that in nearly all cases the 50L6 tubes are wired in parallel,, so when there is a problem with one ,, all current passes through the other one and killing it by default.   This is only what i recall from early this morning reading up.  
there is a mod to rewire the 50L6's in series so that when one goes,, the other simply does not operate but it does not get killed.

i am trying to apply all the things ive learned here and from terry,, so tell me if i am tracking this correctly.
