Before my time Tom, before my time. I had heard of the legendary 630 by the old timers in the TV trade when I was the young gun in the 70s helping the old guys with transistors, but had never seen one until maybe 10 years ago at a swap meet. My dad was fond of servicing them.

But I remember my dad and older brother replacing flybacks on RCA color TVs we sold that were still within warranty - the nastiness peaking about 1968 or so. Back then, RCA supplied parts, but did not pay labor to servicing dealers.

Getting off the topic a bit, but I remember when RCA introduced the XL-100 in 1971, they allowed the owner to have *any* service company repair an XL-100 in warranty. That was short lived and they went back to standard ASCs a year or so later.
