That is a nice, sharp picture from your set, Bob.

The 30A1 chassis used in the 30Axx sets like UberVacTuber's uses two peaked IF frequencies for a "double-humped" response. I haven't aligned one of these yet, but I expect it won't have quite as good a response. On the other hand, this wide a response can be a bad thing. When you feed a color signal into this set you get dots - I think from the 3.58 MHZ color sub-carrier. Later sets had a color filter circuit of some sort I believe. I read about a workaround elsewhere on VK to use the green component output of a DVD player fed into an RF modulator. It worked great for me

Ugh. I have not seen a dot pattern like that before. Waiting in my queue is an Admiral 24C15, which has a 20B1 chassis according to Rider's. I wonder if it will have the same response to color signals?
