I’m in the process of repairing my Sonos ZP90 which has suffered a power surge. I have been much helped by this websites’ instructions https://www.ifixit.com/Guide/embed/61573 and have now removed the power board. I’ve found the fuse has blown and a thermistor has failed. The thermistor has markings SCK 102 which I’ve found here https://www.rapidonline.com/tks-sck-102r55ms-2-5-ohms-5a-ntc-inrush-limiter-thermistor-26-7614 . The site lists several versions with max current (1,2 & 5A) but I don’t know how to determine the correct amperage spec – can some help?
Also I’ve found replacement fuses 250V 2A of this size 100mmx3.6mm but is it a slow or fast fuse?
