Hi. Got an ATC221 RCA set (D52w20YX1). Had no green image, just raster.
Green crt board cold. Replaced board, got green back but tube is weak. Has
anyone got one of these sets due for scrapping with a theoretically good
tube? I can get new but customer doesn't want to spend too much.
Understandable. With new sub number for ATC221 green tube, it is same as
ITC222 green tube. If anyone has one to sell I would be quite grateful.
