  • 990 Instruction. Service Manual & Tube Data Chart
  • 990 Schematics

These titles reproduce the source bundle listing. Repeated identical entries are combined. A title that names several models is shown in full so you can see the stated coverage. This page does not imply that document types absent from the list are included.

Choose the right reference

Compare the complete model designation on your equipment with Mercury 990, including any letter suffix. A similarly numbered instrument or later revision may use different connections, components or test settings. Check the document title and applicable revision before using a procedure.

Operating instructions explain the controls and normal use where they are listed. Schematics show circuit connections; parts lists identify components. Tube charts provide test settings and should be read together with the instructions for the matching tester. A data sheet or chart alone is not a complete repair manual.
