There are a total of five aluminum shields on the 70 chassis. Those shields are spun on and cannot be removed without destroying them. The smallest ones house the IF transformers. The other three are for the antenna, RF (detector) and oscillator coils, respectively.

I redid a 370 Lazyboy a year or so ago. I'm still not satisfied with its performance. I should contact Etech and get his paper on converting the early 70 to use AVC. Ed Locker and I came up with a circuit to do that, I'd like to see if Etech's method differs.
