C1458C Datasheet PDF – NEC
Jan 28, 9, C158c is a CC. Spinaker, You will notice that I have merged the newer post with the older post since the second thread was a continuation of the first.
You might find that one or more of the transistors connected to the output is shorted. Nov 13, I started reviewing the lessons on op amps on this site because I think the problem with my Tek scope power supply is a bad op amp. Nov 13, 4. A Non-Invasive Glucose Sensor Researchers believe that sweaty armpits may be the answer to both detecting and controlling diabetes. Can I use a flyback transformer in a forward topology? I suspect that the op amp in the circuit is bad.
As the -8volts drops the positive input to the opamp begins to go positive. Posted by Gamedojo in forum: Bottom line, compare the datasheets of the op amps for compatability.
What voltage do you measure across capactors C and C? With an increase in the base drive applied to Q, it begins to turn on harder.
The trick to the -8volt regulator stage is that Q is acting to control the positive-most end of the 15V secondary transformer winding so that it is exactly 7 volts positive when measured with respect to ground. Nov 13, 9. Oct 29, 7, 3, Your name or email address: Jul 17, 22, 1, Discussion in ‘ General Electronics Chat ‘ started by spinnakerNov 13, I have it working. Do you already have an account? The voltage you measured across C was around 15 volts. If you imagine that the load on the -8V output increases then the -8volt output would drop slightly toward 0v.
This results in a restoration of c11458c -8volt output datashheet that the droop due to the increased load is cancelled. In the meantime, I will use the values you have measured.

Is this a good enough test for U A and B in t his schematic? I am trying to fix my Tek scope power -8 and power supply.

Can U use 2 transistors in place of a relay to switch 2 different voltages Posted by icadj in forum: First off it was probably not necessary to start a new thread since members are going to dayasheet a bit confused between the two.
Just so that I am clear. This will help prevent confusion since replying members will be less likely to be confused. But would want to run ti by the folks here anyway.
