Hi Jeremy,
you can try asking the group WatkinsJohnson at groups.io. If you have problems with the unit, may it helps uploading fotos there in the file section.
good luck for the research

Betreff: [Premium-Rx] CEI Standard Frequency Multiplier [Was: Watkins-Johnson WJ-8969]
Speaking of CEI, I’m still looking for a manual or schematic for my CEI SFM-1 Standard Frequency Multiplier. Leads to documentation for this surprisingly scarce instrument will be sincerely appreciated.
