[time-nuts] Re: FEI FE-5060A Literature?

[Clint Jay]

Hi, there's a link to information on the Time Nuts archive:

https://time-nuts.febo.narkive.com/Bhntgkdy/changing-fe-5650a-frequency

Schematics might not be included, FE seem to have kept those close to their
chests.

If the link to the ZIP file fails, archive.org might still have it.
