So I finally got time to start working on the 42-380.

I was just going through the third I.F. transformer can and noticed that there are a couple small capacitors that appear in the schematics that do not exist in the actual can (part 34b and 34d, both 100pf caps).

I remember from the 42-1008 finding a similar lack of capacitors in the I.F. cans.

What gives?

It's not how bad you mess up, it's how well you can recover.
