Got the G-2000 today

[captainmoody]

Well I finally got the Rca home today and took a few pics of it.
The guy that outbid me on ebay backed out and the seller gave me a second chance offer for 100.00.
Turns out it was worth the money, Has original owners manual, Service manual, Bill of sale, Dealer tags and remote!
When I took the back off at first I freaked when I saw what looked like a dreaded brightner on the original crt, It turned out to be an isolation only transformer, Possibly due to a heater to cathode short.
The set played fine however with great brightness and color so I won't worry about it.
You have already seen the front, Here's a shot of the backside.

Another interesting thing is this tag RCA made for the new owner.

I'm curious about this set. Does the digital tuning use on screen display, or a seperate display? Can you post any pics of the remote and tuning controls on the set? It would also be interesting to see closeups of the tuner and control boards and maybe a scan of the control section's schematic. Is the chassis at all similar to the CTC-40 apart from the tuner?

Holy faruk! :eek: That mess of wires reminds me of a show where the guy is trembling with the sidecutters and has to cut one wire to de-fuse the bomb and if he cuts the wrong one....well you know the story.

That is quite a console Captain. Those must have cost a few bucks. Is that enormous box on the left the computer to develop the on-screen displays?

No osd, But has electronic tuning and remote. Chassis is a ctc47. I have never seen one of these before and used to service a lot of sets. Guess there were too many poor people in my area!
I am going to go through the manual and see what they used for components and how the tuner is engineered.

Hello i also have a g-2000. the crt on mine is a little weak. as for the chassis, the main difference from the ctc-40 is the interface circuitry for the electronic tuner, and the motorless, voltage-controlled remote circuits. Also, the hi voltage circuit uses a quadrupler, instead of a 3cz3 rectifier tube, and a MUCH smaller flyback.

The tuner does NOT use a standard varactor circuit. it is operated by applying a 16 volt (i think) supply to one of 13 SEPERATE inputs on the tuner. this biases the approiate diodes in the tuner, to operate the correct inductor channel for the desired channel selected from 2-13.plus uhf. the control assembley uses TTL LOGIC(such as a 7400 series ic), and clock circuits, that must have power to "remember" the channel last selected. As for the display, it is a light bar next to the door. ,of seperate bulbs from 2-13 channel indicators.

the remote circuit uses MOSFETS, as "memory modules", to recall the settings of volume, color, and tint. , BY CHARGING A MOSFET THROUGH A CAPACITOR, AND A NEON BULB, IT DEVELOPS A "MEMORY VOLTAGE, WHICH DETERMINES THE LEVEL SELECTED, BEFORE THE SET WAS TURNED OFF.

the set sold for around $2000.00 ,in 1969,1970. this was a LOT of money back then, and only 2000 were made. it was advertised as a "special tv, for 2000 individuals, that had $2000, to take a leap into the year 2000.

the set is primitive, compared to 2000 models, BUT AT THE TIME, IT WAS WAY AHEAD OF ANYTHING ON THE MARKET.

I had to go to pennsylvania, to get my set. and, in over 16 years of repair, i have NEVER worked on one for a customer.

by the way, i have the rca manual, titled the "two thousand"technical manual. it came with my set, when i got it last year. and, my screen name comes from the set, as i waited over 20 years, to get one.

Sounds to me like the RCA G-2000 Fan Club is born. I wouldn't delay this momentous event waiting for a third member to come along. By the sounds of it, that could take a while. ;)

Congratulations Captainmoody and RCA2000.

I'm reading through the technical manual that came with my set, Yes it is very interesting to say the least!
Never worked on anything like it before for sure.

[rca2000]

I agree that the set is vrey interesting. Can you imagine, how technicians, back in the early 70's must have felt, trying to work on that computerized(although very primitive computer circuits)set, when solid state tv was still a new thing?, it must have caused more than a few headaches, just like plasma and hdtv does for us today!

By the way, if your remote needs a battery, IT IS A SIMPLE "AA" BATTERY!! I ORIGINALLY FIGURED IT MIGHT BE A 22.5 VOLT BATTERY,OR SOME OTHER ODD VALUE, BUT IT ISN'T!!

if you ever need a quadrupler, i saw a couple on the net , ecg 536a, still available. I intend to pick up one soon in case mine fails, (which it could do anytime.)

I was one of those techs. RCA conducted a service seminar early in 1970 on the 2000, which I attended. This was supposed to be the future of TV. They handed out a very slick book describing the circuitry, troubleshooting, and theory of operation. Unfortunately, my copy is lost.

We didn't have headaches servicing it, though. The company I worked for (a high volume chain) got ONE. We had it in the shop for a few days studying it. They had trouble selling it due to the high price, and never got another one. I never had to service one, and never saw another one anywhere! You have a very rare piece of TV history.
