Hi Menahem,
?
Since those are NTC thermistors their resistance will depend on the
temperature. They are usually rated at 25 ¡ãC. Then again, they are not
critical.

Hi all,
I'm repairing a dead 2465B - normal high-ESR caps, etc.
Basically finished the job, but I routinely check the following - actual
measurement after the "dash":
R1010 15ohm - open?
RT1010 7.5 ohm - 12.8 ohm
RT1016 5 ohm - 8.2 ohm
R1019 15 ohm - 22 ohm
I've replaced the 15 ohm Resistors.
1. Should I replace the 2 RT's, or are the readings acceptable?
2. Is an acceptable RT1010 substitute - Digikey 495-3052-ND NTC?
3.?Is an acceptable RT1016 substitute - Digikey 495-3051-ND
NTC?
