trinitron find

[ampegdan]

Hi all-
Found a Sony KV-1926R 19" Trinitron, April '87, in a thrift store today. Works absolutely perfectly. Replaces same model I've had for several years in the kitchen, whose picture developed a pulled-in look at the sides and was emitting a high-pitched ring. I really like these TV's, does anyone have any opinion on them? Not knowing much about this sort of thing, would the old one be worth repairing or should I keep certain parts for spares and chuck the rest? Also, is it possible to convert these for use through a receiver with surround? All mine has is the rabbit ears and the cable coax input.
Thanks
Dan
