Slow and ready as she goes. Took a minute to figure out that the heatsinks are directional, installed first row of outputs from right to left (transformer to input jacks) mj21196/rca66546/mj21196/rca65546 along the bottom row using silipads rather than mica and grease. verified no shorts collector to ground.
Went through the entire backplane once more looking for any metal fragments and checking for possible contact point interference, found the second cold solder joint on one of the emitter resistor tie down points and re attached. Re routed the input wiring to run along the side of the unit next to the speaker relay. Left side done, out of time for the day. Will mount all the TO-92 heat sinks once the right side wiring is done just before start up on the dbt. Getting real close now.
