Still working on my Sylvania

[Mick AV-8]

Hi John,
Do you mean that it wont matter in the fact that I cut out and put back in the old wax cap?
Or I wont matter ..if I replace the old with the new cap?

Is the HF adjustment the little screw comming out of the back of the chassis?

I meant that it won't matter that you took the old cap out and put it back in. I'm reluctant to refer to it as "old wax cap" because that sounds like paper to people when this one is polystyrene.

Yes, it's next to the size switch. That's the top core which is labeled horizontal hold on the diagram, and the bottom core is on the inside and that's the phasing.

When you get to the point where you need to touch up the horizontal hold you want to remove the 6AL5 discriminator tube and adjust the hold until the picture is nearly normal and moves slowly across the screen. Then when you replace the 6AL5 it should lock in and be stable as soon as the tube warms up. That 6AL5 has a 4.5 ohm resistor in series with it's heater. It may be bad or at least increased in value. You should probably check it. It's meant to keep the 6AL5 from heating up as quickly as the other tubes and gives the horizontal a chance to get close to the proper frequency. Otherwise it could lock in on a harmonic. Not likely, but possible.
