[Tig] Ursa Shading

[sklein54 at earthlink.net]

Hello Steve. What you brought up brings back memories. I remember Rank & aftermarket tubes being very inconsistant when we were using these machines in Los Angeles. Disabling scan-tack we were able to find a sweet spot sometimes but it would burn the tube even faster.
Dude. how many of us took out the tweaker you had to have in you pocket to adjust parabola on our 3C before work each day?
