I recently junked a '78 KV1911 because it had a weak CRT and other chassis problems and I have seen many Sony's from that time period with weak CRT's. Most would have a strong green gun while the red and blue were dead. One plus is that I think the KV1922 is new enough to use a BJT horizontal output transistor instead of that horrid SG-613 (or whatever it was) gate controlled switch that cost out the butt and is very easy to blow.
If I knew before hand that the CRT was good, I'd probably grab this set. Of course, finding out the condition of the CRT before winning the auction may not be possible. Many times, their idea of a good picture and mine are two different things. There may be some bad electrolytics that need changing, which should be no big deal as long as you have a good tube to work with. BTW, weak Sony tubes usually don't rejuvenate well, if at all.
