While you have your scope in there verify that the saw tooth frequency at the grid of the horizontal output tube is correct.

Yes the H hold works normally. I have the Horizontal hold control optimized at the center of it's range, and when you adjust the control the stable image (and the vertical band) will shift slightly left and right depending on which way you turn the control. IE: it seems to be working perfectly normal.

Next step is to start looking at the wave forms in the article you posted.

BTW, what should the frequency be, at the grid of the 6BG6? 15.734 Khz?

I may not get to that today. Got some other things I need to do.

Thanks for your help,
