Not sure exactly what you need.
KCS205A is the CHASSIS number. It could be used in
many different models. It is listed as Sams 1859-3.
Let us know what you need or what is wrong & we will
help out. RCA B&W's from this time were very good sets
& had few problems. As far as electrolytics go no reason
to change them all, just failed ones.
