Hi Hue

Were those octal phase shift networks hermetically sealed or in a vacuum?

If either, then the resistors may be fine as they are not exposed to moisture.

I have an unused B&W octal base, audio  phase shift thing like in this  xmtr. Knowing now about how miserably the old carbon resistors like to drift from nominal values, i do wonder how far off usable those phasing networks are now.
