white relays

Tell us about these relays; I think it was you who referred to them as
'white relays'. What kind of relays they were? Encapsulated reed, I would
think.
No - special low capacitance relays made by Tek, e.g. part # 148-0054-00.
If you look inside a 7A12 or 7A13 they are obvious.

What kind of failures did you experience with them? Were coils
failing or contacts did not do well in these super dry circuits.
The armatures get stuck.
