From: wb8foz@fmsystm.ncoast.org (David Lesher) Subject: HP 200CD manual Reply-To: wb8foz@scl.cwru.edu Organization: F M Systems Medina, Ohio USA Distribution: na Lines: 14 The 200CD is one of three oscillators that HP made many years ago. (The others were the Low Frequency Oscillator and the Wide Range Oscillator.) These are the ones with the 7" diameter chrome dial, a Wein Bridge circuit that used pilot lights as the feedback loop, and firebottles that produced many volts of output. I've just acquired a pair of these venerable old beasts. The non-working one, SN 605, (owned by Crosley Radio at one point!) needs help. I know I can likely buy a microfiche copy of the book from HP, but that costs.... and considering I paid a dollar for the pair in the rain at the Dayton Hamvention;-} Does anyone have such a book they could copy parts of for me? Thank you....
