Kortek KTN-20!

[Mrhide]

So after the 39 inch, I powered that small 19 inch:

though it was a hantarex but no, it appears to be a kortek? unsure of the model... anyone? @nem

so anyway, on power on, total vertical collapse. (no picture)
checking it out, I see that the big snap cap is ballooned. happen to have an exact spare and voila, vertical collapse fixed:

well .. almost 100%: The top 1/2 inch can't line up. I changed a few caps that I had but still the issue remain. That is a cap issue yes?

thanks!

Kortek KTN IIRC.
A blast from the past!! With these, it's best to re-cap it totally.

These are not bad when they work , but keep an eye on the flyback - they like to go up in flames on this model haha

That should go away if you adjust horizontal hold.

That should go away if you adjust horizontal hold.

It does not… the line goes left or right but never aligns properly. Caps should be here today so we’ll see if that fixes it or if it’s something else

Might just be a quirk of the chassis.

Full cap = no changes.

Will try changing the pot

Edit: nope. Not the pot
