PARTS LIST
EXPLANATION OF PARTS LISTINGS
This section contains listings of component parts used in the Inovonics
DAVID-II FM-Stereo Processor/Generator. These are listed either en-
masse, or by schematic component reference designation, and may, or
may not, specify a particular manufacturer. When no manufacturer is
called-out, the term “open mfgr.” advises that any manufacturer’s
product is acceptable.
If a particular component is not listed at all, this means that we do not
consider it a typical replacement item. Should you need to order an
unlisted part, call, write or FAX the factory with a brief description and
we’ll do our best to figure out what you need and get it on its way to
you.
PARTS LISTING
Unless specifically noted by component reference designation below,
capacitors are specified as follows:
a) Under 100pF are “dipped mica” type, DM-15 (or CM-05 military
series) size designation; “P” value is picofarads, ±5%, 200VDC;
(open mfgr.).
b) 100pF to 0.47µF are of the metalized mylar or polyester variety;
whole number “P” values are picofarads, decimal values are
microfarads, ±5%, 50VDC or better. The style used in the DAVID-II
is the “minibox” package with lead spacing of 0.2 inch. Preferred
mfgr.: Wima, MKS-2 or FKC-2 series. Alternates: CSF-Thompson
IRD series or Roederstein KT-1808 or KT-1817 series.
c) 1.0µF and above are radial-lead electrolytics, value per schematic,
25VDC; (open mfgr.).
