Vertical Deflection Amplifier for Oscilloscope
The vertical deflection amplifier uses a 180 degree phase splitter to generate a differential signal. The CRT requires large drive voltages, but almost no current. The oscilloscope bandwidth is limited by the amplifier chain as almost all electrostatic CRTs have...
Restoration of the DuMont Industrial Color Monitor
The motor control chassis lacks a coaxial input, raising doubts about the presence of composite sync, particularly given the length of the cables (5 or 6 feet), which may eliminate the possibility of a sync pulse for the red field....
Corrector circuit diagram of an analog circuit
A XICOR X9241 POT IC module can be utilized to modify the four digital analog circuits, as depicted in the schematic.
The XICOR X9241 is a digital potentiometer integrated circuit designed for precise adjustment of analog signal levels in various electronic...
CRT and Power Supply for Oscilloscope
The high voltage section of the CRT is unchanged from the original vacuum tube oscilloscope used as the basis of this design. The CRT requires shielding from the main power transformer. Cold roll steel around the CRT does not provide...
CRT final video driver amplifier
The CRT final video driver amplifier is a complementary push-pull final video driver amplifier composed of three transistors. VT511 functions as a driver amplifier, utilizing a common emitter configuration that offers high gain characteristics. The input signal from the polar...
Analog circuit enforces slow servo response
The all-analog circuit presented controls the rate at which a miniature turbojet engine can be throttled. Increasing or decreasing the throttle too quickly on a miniature turbojet engine, or any jet engine, can lead to quick failure in flight, causing...
Crt yoke driver
A 500 mV peak-to-peak triangular waveform centered around ground is applied to the amplifier, resulting in a peak current of 100 mA flowing through the inductor.
The circuit involves an amplifier configured to process a triangular waveform signal with a peak-to-peak...
