kamakiri's CTC16

[drh4683]

This is the ctc16 that kamakiri had. It was built late in 1964 but being a ctc16, its a 65 model year. Got it a couple days ago. Had some problems, no vertical sweep, horizontal shrinking and color sync issues.
Got it all fixed up this evening to 100%, some voltage tests indicated no plate voltage on the vertical oscillator. Traced down to an open 1000ohm 3W resistor in the vertical B+. Got the vertical sweep back but then had severe horizontal shrinking which was traced to a high resistance short in the 80uf 450V filter cap. The result of this short resulted in about 120 volt loss in the B+ to the horizontal output thus dramatically reducing the horizontal drive voltage to -30v, supposed to be -56v! The flyback looks perfect yet, not even a drip of was in the cage and its the original! The set definitly got many years of use. Had to fix a few cracked solder joints on the deflection board to cure some "jittering" issues.
The easiest part was changing many tubes! The ctc16 uses 2 6GH8's which were bad of course and a defective 6JU8 color AFC, which you can always count on being shorted.
After the repairs the tv was aligned, horizontal efficiancy, HV etc. Focus balances in the mid of its rotation with outstanding results. Once again, another RCA with that razor sharp color picture!
