TECHNICAL DATA Orban Model 6200
Parts List
Parts are listed by ASSEMBLY , then by TYPE , then by REFERENCE DESIGNATOR .
Widely used common parts are not listed; such parts are described generally below (ex-
amine the part to determine exact value). See the following assembly drawings for loca-
tions of components.
SIGNAL DIODES, if not listed by reference designator in the following parts list, are:
Orban part number 22101-000, Fairchild (FSC) part number 1N4148, also
available from many other vendors. This is a silicon, small-signal diode with
ultra-fast recovery and high conductance. It may be replaced with 1N914
(BAY-61 in Europe).
(BV: 75V min. @ Ir = 5
µ
A; Ir: 25nA max. @ Vr = 20V; Vf: 1.0V max. @ If
= 100mA; trr: 4ns max.) See Miscellaneous list for ZENER DIODES (refer-
ence designator VRxx).
RESISTORS should only be replaced with the same style and with the exact value
marked on the resistor body. If the value marking is not legible, consult the schematic or
the factory. Performance and stability will be compromised if you do not use exact re-
placements.
Unless listed by reference designator in the following parts list, you can verify
resistors by their physical appearance:
Metal film resistors have conformally-coated bodies, and are identified by five
color bands or a printed value. They are rated at 1/8 watt @ 70
