I got a 1952 RCA console TV I have Gutted the old CRT and chasis. I am going to replace the CRT [ TV TUBE] with a computor monitor and a cable box. I'll drill a front door peep hole viewer in front of the cable box IR sensor for remote control. I make a new custom trim plate for the new " picture tube" and I would like to use the old 8" speaker. Monitors have a more square shape than LCD TV's which is closer to the round tubes of the fiftys. Using a cable box would allow me to place the Peep site where I want it with relation to the cabinet.
