They are the two voltage regulators, with the two trimmers, resistors, and half the didoes, mounted on a piece of perf. On the right of the same picture, we catch the edge of a big tube of heatshrink, containing the two 470uF caps, and the other half of the diodes. The 10uF caps are on the main board.
Yes... you read correctly.
It's a carbon copy of the PLL's power section, but in bits and pieces, wired together.
And, I had that nail done up special for this shoot.
