Ra53 thermistor

WebApr 13, 2024 · So, using the RA53 and a NE5532 op-amp, it only took about an hour to make an oscillator that ran off a couple of 9v batteries, and measured about 0.007% THD at 10kHz on my analyser. (The remaining THD is probably a combination of ignoring Williams’ Law, thermal modulation in the thermistor, and the dirty mains in our lab.) 7. WebFeb 18, 2024 · Here there was an Open University oscilloscope and function generator, very low spec and now rarely seen, but it did contain an RA53 thermistor. Then there's ebay. Years ago I fixed a Far Eastern made audio signal generator which looked as if it was intended for school and hobbyist use.

WebSep 4, 2024 · Yes a Thermistor was a popular choice for gain control BUT the RA53 thermistor is now unavailable for love blood or money. HP switched from bulbs to FETs for gain control around 1968. The upshot of this is that the HP 209A Sine Square Generator uses a FET and some feedback to minimise distortion. http://www.seekic.com/circuit_diagram/Signal_Processing/Oscillator_Circuit/index29.html
