Sylvania Hybrid D16 - low h-drive

[DavGoodlin]

After testing the resistors and finding several out of tolerance, especially those machine-inserted half-watt resistors, I then just replaced all orange and dk green drop caps.

I measured the old caps and they too were way off. The new mylar caps were right on, using my Fluke 177. It seems, with all these off tolerance values, vertical sweep and of course convergence would have been greatly affected.

After a power-up, vertical hold was right in the middle of the control range. There is still an issue with the Vert lin control being maxed out just to get enough sweep at the bottom. Maybe its time to try a tube, though the 6LU8 looks new.

An initial set-up of convergence showed the R/G vertical lines going to 1/2 inch apart at the bottom of the screen. After tweaking the right side R/G vert coil, I was able to readjust the static and get the bottom issue much better. The R/G vertical lines at top and left have good range and adjusted easily.
