    LM399H is the heart of the instrument. It's the oven controlled voltage reference. It's what ensures low drift and accuracy of the whole instrument.
    Also those flat upright things you couldn't tell what they were are laser trimmed resistor networks. Very unique and important/expensive components.
    Thanks for the teardown!

    Hello I have the Fluke 8808A ... I did the measurement of a transformer for tube amplifier and the voltages were higher than 700V AC. The multimeter broke. Ohms and AC function fail. Any suggestions or help ...! Greetings.
