I carefully removed the rather ugly non-original aqua green spray paint from the front panel and repainted with the original gray. An engraved panel makes it possible to properly restore the control markings. After the paint had thoroughly cured, I used "liquid paper" "white out" that is normally used for covering mistakes on paper to fill in the engraved markings. Excess white-out is removed with gentle rubbing of waterless hand cleaner on a cloth.



The power supply on the SP-200 is separate. It did not come with this set so I built one to provide the required 380 volts at 50 ma, 250 volts at 100 ma, 100 volts at 10 ma, -50 volts at 11 ma, and 6.3 volts AC at 7.5 amps. The power supply with its little rack cabinet is visible to the left.
