Searching for thermistors to repair a uW power meter


DD1US
 

Dear all,

 

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.

 

Kind regards

 

Matthias
