Rauland 10RP4 CRT, 10BP4 substitute Vintage TV Television Tube CBS 12CC2

Description

Here is a Rauland branded 10RP4 CRT in excellent condition. The tube was pulled out of a decommissioned black and white tabletop TV. The tube tests very near would expect a new or NOS tube to test and has NOT been rejuvinated to my knowledge. Emissions come up completely in about five seconds, life tests shows significant drop in emissions only after about seven to eight seconds. Good cutoff and no shorts. Screen has a couple of very minor blemishes, no scratches or gouges. Grid element in neck shows no bluing typical from extensive use with an in tact getter.
This CRT was being used in place of a more common 10BP4. The 10RP4 is a specially designed tube for CBS field sequential color sets, notably the CBS model 12CC2 and possibly others. Tube will be packed extremely well. I'll do my best to answer any questions or make any additional tests.
