Beolab 2 NTC thermistor value

[axel73]

Hello everyone,
I’ve just bought a knowingly non-working BL 2 (red LED) on internet:
When turning on my Beomaster 7000, the BL 2 LED briefly goes from red to green and back forever to red (with the clicking sound of a relay).
The Powerlink cable used for this setup was tested on my Beolab Penta and is working correctly.

After opening the BL 2 I’ve discovered that the previous owner tried to replace  the NTC thermistor screwed on the back of the woofer.
Since I’m not sure that it was done correctly, I would like to make sure that the right NTC thermistor was used.

Could someone please tell me what should be the value of this NTC thermistor at room temperature (around 20°C)?

Thanks for your help.
Best regards,
Axel
