I just bought a Lampkin 107C Service Monitor. It has an accessory
that I didn't get. It's the 20DB attenuator pad (part No. FAP-20).
Does someone have a schematic available so I can build one? I'd also
buy the unit itself.

Pomona Electronics will still sell attenuator pads. Or you can make
your own up; the schematic is in the ARRL Handbook.
