Surprisingly little. It was more conservation than restoration. No original components in the main chassis' were changed. A few modern resistors and capacitors from work done by the RCA engineer in the 1980's to the vertical chassis' were put back to original. Even in the SPU, components like the filter caps are film type and are all still original. A few power resistors (50-100W) were open in the SPU.

Just as with the incredible luck of rescuing the set days before it was to be scrapped in 1984, by an incredible second stroke of luck, much of the original documentation and ephemera for this set was obtained a couple of years ago at a pawn shop in Tucson, placed there by the daughter of the engineer that was in charge of this project at RCA.
