got the g-2000 today.

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.
