IMHO that chassis was RCA's best. Always had a great pix when done.
Never junked one.
Add to the common list IIRC CR4118. Its an 18V rectifier off the
switching transf. Causes very subtle intermitant color & video
probs. It was a change in every repair part. Also one or two
'had the same P## so those got changed too. Should be still around as RCA NOS.
