[R-390] R-390a Refurbishing questions

[Jacques Fortin]

Hello Gary,

1_ RF rack springs: I still have some spares that I can send to you if you
are willing to pay for the postage.
2_ Argh: shit happens, isn't it ? Is it a RF or an IF slug ? As you can
remember, they are not interchangeable.
The RF ones (red and white dotted) have a relative permeability of 10, the
IF ones (more greenish or having green dots) have a relative permeability of
4.
Yours was used in which rack ??
3_ The "comb" should be below the junction of the RF and the 2nd crystal
oscillator chassis.
I never take picture of the "naked" chassis when I restored my three sets (I
should have), but it makes no sense if the combs are not contacting the RF
chassis edge.

For the slug + spring, let me know.
