Predicta Holiday - First power up attempt

[madlabs]

Hi All,

Been taking a break from the Predicta for a couple of weeks. I needed a break and I had a couple of ham radios on the bench for other folks that I needed to get to. In the meantime I managed to pick up the parts set and complete set that I bought a few weeks ago.

Luckily, the parts chassis has an A11/12 that appears good. Didn't ohm it yet but the slug is intact and moves. So, I plan to remove it and install it tomorrow. Since I have to take the PCB off again, I am wondering if I should remove and test the ceramic caps. I now have a Heathkit C3 capacitor checker, which I did not have the last time I had the PCB off. I would like to track down any problems that might be the cause of the vertical linearity and horizontal hold issues I am having. Any thoughts on that? Any particular culprits to look at?
