Thanks. That's from an Admiral 24A12 with a 20A1 chassis which uses a staggered tuned IF for really wide bandwidth with a flat plateau.
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
