Yes, the 103A is the Frequency Comparator; the 203A is the Distribution Amp.
Sorry for the mistake.
The 103A manual price as listed, is $25 plus shipping. I received
confirmation this morning that is indeed the Montronics Frequency Comparator
manual with schematics, so I ordered it immediately
(http://www.manualsplus.com). Don't know how many they have in stock.
