Although the scope and frequencies look right, the best test is to try the 25.75 MHz modulated video and audio on an old set. Attached are some pictures. First I hooked the VA62 up to the antenna leads and sent video and audio on channel 3, the first two pictures.
Then, in the last three pictures, I hooked the modified VA62, set to 25.75MHz, up to the third, second, and first picture IFs and set the VA62 levels accordingly. It worked!
