that same crt was used in the aa series chassis up to 88!at least that is the newest set i have seen.
used up a lot of solder and wire jumpers fixing the griplets on that double sided board.

I had one of those back in the late 70's. I got it from a TV repairman friend of mine.

It had a bad heater on one of the guns but I was able to get it working by whacking the neck of the CRT with a screwdriver handle.

I had to do that a few times but it finally seemed to take and worked for quite a while before I sold it at a garage sale.

It must have been an early one because I remember it had a really coarse dot pitch and really lousy color!

Later I had a 71 or 72 RCA XL-100 19" portable which I seem to recall was one of the first sets to use a slot matrix 110 deg CRT?
It was a solid state modular set and had great color.

correction edit
the first was probably the ctc74.
they were modular and folded down like a truck tailgate for service.
i remember that rca .
it was not an inline but looked like one.
110 degree small neck delta gun.
i think the first inline slotmask was in the ctc 88 (the chassis reminds you of a basket)

Here are my other PortaColors. The one on the left is from about 1972 and the one on the right is from 1974. The one on the right has a bad osc transistor in the UHF tuner. Can you believe that the only transistor in the entire set failed.

Here's a couple of early 70's sets that would have been competing with the portacolor. The one on the left is a solid state sony KV-9000 9" and the one on the right is a Panasonic 'Pana-Color' 12" hybrid with a solid state tuner, IF, and chroma, but everything else tubes. Both sets are from around 1972 and produce an excellent picture compared to the GE.

i have several of the kv-9000 sonys and when working right they can outperform many new sets.but to get them right you must change a lot of lytics!

Got this "little" set several years ago solely because of the unusual shape; it tapers to the rear to about half the dimension of the front. Inside, most components are made--and I presume the set--by Sanyo. Odd, too, that a MM like Sears would have sold a solid-state set so early on. The UHF tuner is a continuous-tuning type, no clicks. Note the resemblance to the Portacolor, right down to the red-YELLOW-and blue badge on the front!

here is a picture of my rca 19" table set manufactured april 1976.
this set has very little use on it. has a power transformer and weighs a ton. how collectible are these going to be in the near future... steve

has a great picture bright and razor sharp

Steve, that RCA is the set that replaced my XL-100!

I got it from my friends TV shop, the neck of the CRT had been blown off, supposedly from a lightning strike. It was only about 3 years old at the time.

I replaced the CRT and it worked great.
You're right about the weight, I remember it being extremely heavy!

Drifting way off topic here but... I was given a 1982 Sears 13" portable yesterday. It was headed for the trash.

It works but has some retrace lines, bad caps?

I think it is a Sanyo, I had forgotten how lousy the color was on these, you can have pink orange or green people but no natural looking people

The newest tv in my collection is a Zenith Digital system three 27" (1989 model) that I sold new when I owned my tv shop. Had teletext option with printer and picture in picture. Got it back from the first owner in 99 and still is as new in every way, Unusual for this model as they were plagued with problems! (9-700 module) I fixed a lot of these. One of my favorites is a 1979 system three with zoom (remember that!)Not a portable but worth mention. It's a really neat console that will fit nicely into the corner of a room as the cabinet is semi round with a cool silver front ( Very 70's!) I'm sure someone remembers these! I have 2 of them presently. Still an easy trash day find. And are already picking up in popularity. I sold one 2 yrs ago for 300.00 in clean, working cond!

Captainmoody, when you mentioned the problems those early RCAs had with circuit boards becoming brittle over time from heat, it reminded me of a similar set (marketed by Silvertone in the early Sixties, with the RCA CTC12 chassis) I owned over 30 years ago. The set worked well for me until 1973, then I had to replace a tube (a 6GH8 video output) and--wouldn't you know it (darn it!)--the socket broke out of the board and clunked to the bottom of the set.

(OT now, but it sort of ties in with the foregoing)-- RCA's newer sets (at least the CTC185 chassis) seem to have the same problem. I bought one of these sets in late 1999 (RCA XL-100, CTC185A7 chassis); although it works well on cable and has a beautiful picture, I have had to have it repaired twice for the same problem: the RF connector to which the antenna or cable connects breaks off the tuner PC board if you put the least little bit of pressure on it.

The technician who repaired my set told me this is a weak point in the design of this chassis; I hope this issue has been addressed and corrected in the newer models.

come and pick up the rca that i have the picture posted. you will be darn lucky if you dont have a hernia. do we need to go to another board to talk about tv sets. steve

I see quite a few of the CTC 175 to 187 models out in the trash, If they are the 27" to 32" stereo variety I pick them up! Once the ground connections are soldered, And on occasion, An Eprom replaced, Those sets work great! Great picture quality and quite reliable once repaired. I have sold a few on ebay with good results. With the money I make from those, I can then buy my vintage goodies!

While the older the better, I do have some interest in hybrids and early solid states. The number of hybrid sets made has to be small compared to even 21" round screens. I'd participate in a group for late tube and to early solid state TVs. Such interesting things as sony's 7" chromatron would fall into that.

That RCA you posted has an identical cabinet to an all tube one from the late 60's that was given to me about 10 years ago. I was probably in junior high at the time. The set did work, but the CRT was weak so I didn't keep it long. It had one of those low focus voltage CRTs that were popular in the late 60's. RCA referred to it as an einzel lens system. It's interesting that these CRTs only require at most a few hundred volts to focus and it isn't dependent on the HV. However, I've never seen one with very sharp focus and they seem to go out of focus badly with age. The usual lack of a real focus control doesn't help either. I think this RCA had a 3 or 4 position jumper.
