Soft turn on for old color unit for color??

[Pete Deksnis]

As I saw it, the Thyrite in the CTC10 was there to limit the filter cap initial charging current, protect the power supply diodes that have to pass the high current surge of the filter caps, and even as a secondary benefit, the on-off switch sees much less turn-on stress. It also gave me a warm fuzzy when I watched the #47 lamp ramp up to full brightness in the two seconds or so that it took, because all the filaments were slow-starting too. To me Thyrite is a Stress Tab for electronics.
