So I'm still trying to figure out this weird wiggling and slightly vertical picture on my tempest.
I'm wondering. The 15vdc test point measures 14.5vdc is this normal? I'm wondering if this is causing my weird issues.
 
I usually replace the regulators if the voltages are more than +/- 0.25V out of spec.

The video section will work with it as low as 14.5 (based on what I've seen), but I'd recommend replacing that regulator anyway. However my guess is this isn't the cause of your distortion issues.
 
Thanks

Thanks for the quick response. I think I'll be sending the Tempest out for repair this weekend. Don't have the time to troubleshoot further. This is taking me for a loop.
 
If you have one it's only three pins! I'd try it. I think I had a Star Wars AVG with similar symptoms because someone had put in a 7812 instead of a 7815!
