Here's the bottom view of one with recycled transformers like yours,
I bought it on eBay cheap and finished it up. I spliced longer leads
on the transformers where needed.I tried to use similar colors, and
used heat shrink tubing on the splices. The guy didn't use the barrier
strips, it has turrets, so it may have come from Uncle Ned.
Notice I put aluminum 6/32 RivNuts in the holes that hold the bottom plate
on. Be very careful if you use sheet metal screws, that stainless is
hard, and cheap screws will break off in the holes.
