" Why not use the guts of a cheap TV set?

Be REALLY careful with cheap TV sets. A lot of them have saved
manufacturing costs by using a ploarized plug and NO ISOLATION
TRANSFORMER. They just rectify the AC and use a dropping circuit
to get the various B+ voltages. This can cause lots of smoke when
connecting the internal stuff from the TV to the internal stuff of
your computer. I lost some chips in my 'ol TVT-II from Popular
Electronics a few years ago doing this - then I went to Software! 8{)
