First prototype was started in December The back half of the
supply was totally gutted Transformer Interphase reactor SCR/heat

Slow going on first supply Not worked on full time Many delays
with materials and parts Many discussions and decisions on final
layout High priority on ease of future maintenance Second gutting
for final hole drilling, documenting and installation of plated
parts. Made doubles of many parts

Next bias supply rehab: Much faster! Layout is finalized and
documented. Have 80% of parts and material on hand Few more
in-house machine shop jobs Off-the-shelf electrical parts EE
Support techs working on labor intensive assemblies ~2 month
turn-around on next supply Training full-time worker Ordering
remaining parts Remaining supplies have solid wall separating front
and back, possibly creating a few problems ~1 month turn-around
thereafter
