1957-ish RCA 14T-4074 14" B&W TV set

[electra225]

This is my parent's first TV. We have watched many a "Gunsmoke" episode on this TV. My grandparents got their first TV in 1950. This one is a 14" so it had a bigger screen than the grandparents' 10 inch RCA. The last time I played this TV, it exhibited some vertical height/linearity issues until it warmed up. As I remember, it took a few minutes to fill the screen vertically. It has a 14BP4 picture tube (I think). I wonder if this is one of those sets you have to pull the picture tube out the front in order to get the chassis out. If so, how would one troubleshoot the thing? Is this model picture tube metal? The yoke appears to be not falling apart, and the set is in fair physical condition. The numbers are all worn off the channel knob, but it was like that when I was a kid. By what I see, you would release the gold band at the front of the cabinet, then slide out the picture tube after disconnecting the yoke and picture tube plugs. I'm not sure my TV repair skills are up to one of these, reputed to be not for the faint of heart as far as working on one is concerned. This one may need a new home as well. I should probably add a question mark behind the model number. The sticker is gone, but there is a strip of masking tape on the inside of the back cover that gives that model number. This thing has 14 tubes if I counted right and uses a 6AQ5 for the audio ouput and for the vertical output. It has a power transformer and a 5U4 rectifier.

Can't help with that, sorry (Dave...?) but what's sitting on top of that Dyanco, and what's the amp L of the TV (Heathkit maybe?)

Heathkit. I use it for a bench amplifier.

My parents had this one, in blue, in their bedroom. It was "portable," meaning that it had a handle on top. Around 1959-60 there was some big event and I carried the TV across the street to the school so the class could view whatever it was. It looks close in age to yours.

Note the price. I still have the TV in the storage unit. For that price, sentiment would be no barrier to a quick sale.

On mine, something went bad 35 years ago. By then it was their dining room TV. I found an identical unit and either subbed in the new chassis or the new CRT, can't remember which, and it was working again. The "spare parts" left afterward were donated when I moved.

I forgot to mention, this has the KCS-102F chassis. I need to scrounge up a Sams if I get brave enough to dig into this thing. I haven't checked the picture tube, either.

That's a cute RCA, "portable". The link Chris provided states it's worth over two thousand bucks. Not for this guy, but maybe someone.

I didn't have mine in my 3x5 card catalog but I found my photocopied Sams for it. I have circled Model 14PT8022 on it. It lists chassis KCS 111 A-H and KRS 23A. Just to let you know how long ago I made the copy, its on coated copier paper. That means I paid $.05 per page at the U-M engineering library, which had a full Sams collection. Sometimes the nickels were hard to come by in those days.

The one Chris linked is a little newer than mine, I think. Those were in the 1958-ish range, weren't they? The one I have started in the 1955-ish range. The later ones had cabinets that partially came apart for service. It must have cost a fortune to repair one that you had to remove the picture tube to get to the capacitors on the bottom (front) of the chassis. Silly engineering, if you ask me.
