Swap: CTC11 Video i.f. into CTC10 chassis?

[Eric H]

The video i.f. board in my CTC10 Wynnwood is in grungy condition, it's discolored, the i.f. coils are rotted away and there was a lot of white crud all over it. I seemed to be having video issues as well, low luminance etc.

I have two CTC11 chassis with nice boards and I would like to just swap the whole board but I need to know if there are any issues I should be aware of, like are the input and output frequencies the same?

The only difference I can see is one resistor on the 10 has been replaced with a peaking coil on the 11, otherwise all components seem to be the same.

I have new 12&3 video i.f. coils coming from Moyer so I can fix my old board if need be, or I could install them on the 11 board because the plastic on it's coils is less than great also.

Top board is the 10, note the rotted plastic in the coils on the bottom board!

I think that there aren't problems to swap the boards, only you'll have to make again the alignment.

I figured I'd have to tweak the alignment a little, especially if I replace the coils.

The plastic core is loose on the old board so the slugs were probably out of place anyhow. One of them fell out while I was cleaning it.
