TRK-12 RCA Invoice "AS IS"

[tubesrule]

The Worlds Fair sets were modified with voltage doubler HV power supplies to make the picture brighter and line level inputs. The CRT's in these sets didn't last long and were replaced often. While some of the stuff from this exhibit still exists, (a power supply and the master receiver) I doubt any of these sets were kept or sold off after the Fair.
