Transistor and Deflection board on Tempest - wobbly/jittery graphics

Hi!

I used the transistor and deflection board kit on my Tempest cabaret. Good news is it powers up and Tempest is running. Bad news is my Tempest now has the "jitters" or "the shakes" which it didn't have until I installed these kits (it's especially noticeable on text). Tempest was confirmed working before I installed the kits; I put them in as preventative measures since I had to replace two of the bottlecap transistors a little over a month ago. Just curious if anyone else has experienced this and if there's a fix out there? Overall I love the kit and want to keep it if at all possible, but the jittering is driving me a little batty. I've tried messing with the pots on the PCB but it hasn't fixed the issue.

Thanks in advance!

-Dave
