I have here an old power meter which was apparently built according to a description of Carsten Vieland DJ4GC.
It uses the principle of a bolometer.
Unfortunately, the thermistors are defective and I need to replace them.
They are apparently of the following type: Siemens NTC type K19 nominal 12kOhms
Does anyone here in the group have a pair (or two in case something goes wrong during the repair action) of
such thermistors which he would be willing to sell ?
Also if someone knows a shop etc where to buy them a hint would be appreciated.
Many thanks in advance for your answers.
