Panasonic CT-26

[Dave A]

Cleaning storage today and found a 1971/72 Panasonic CT-26 Pana Color. 13" or so delta gun. 10 tube hybrid. No idea where I got it. Home and powered up minus Variac. It slowly got to to speed and was trying to work with massive dirty controls. CRT looked strong. Tubes seem to be original. Then I moved it and the not connected dipole antenna 300ohm wires brushed the cable balun. Big 110v spark and white smoke from inside below the CRT and breaker pop. Not sure what that was as the antennas are not grounded. Rats.

Looked inside and nothing burned and the line fuse was ok. My power strip saved it. Cleaned while open and powered again. It came back up with a minor AC hum line that was an odd few staggered lines of the scan. 4-5 lines at most. Played with the magnets and got perfect convergence. Grey scale great. Went behind to look for focus control and never found it. When I got back to the front the hum was gone. Did it reform itself? Still need to find the focus to finish. A bit soft. The AFC is wonky sometimes working fine and then garbage. Works fine with AFC off.

Anyone know where the focus is? Don't see any focus jumpers either. The web is no help with this set. Swamped with another CT-26xxxx flat panel.
