Working on replacing the two multi-section twist locs now.
Even though they used twist-locs, there are existing mounting holes with the standing hole spacing for phenolic insulation wafers.
Perfect opportunity to use adapt-a-caps.
Ooops, slightly melted the wire insulation in a few spots

One down, one to go.
BTW those two 12K resistors in parallel is how it was originally built and shown on the schematic. Two 12K, 1W in parallel
I'm thinking 5.6K or 6.8K wasn't close enough?
