In my case, the TH301 thermistor has burnt even without any problem in my electrical installation! One or two days before my Play:1 went dead, its back side was getting extremely hot. I’m not shure, but I guess the failure has something to do with the fact that for 4½ years, I always powered it off by a single pole switch, when not listening to it. Maybe power peaks at each startup wore out the TH301.
And MOV301 doesn’t look very well neither.
I couldn’t read the references anymore.
Another Play:1-owner gave me these, as you can see in the pictures:
TH301 (green thermistor): SCK 052
MOV301 (ocher metal oxide varistor): TVR 14241

The SCK 052 can be found on Ali Express.
The MOV301 in my device was a TVR 07431*, as shown by Ikke Zelluf.
This reference means 7 mm diameter, 431 voltage and D-type (high surge).
Can also be found on Ali Express, but as a regular type.

I had to order 20 pieces of each, for less than €6 in total. Delivery in 20-40 days :-(

Finally, after replacing TH301 and MOV301, my Play:1 works well again, and stays much cooler at the back side.

So far for my answers.
But my question is:
I didn’t find the thermistor nor varistor with these references for sale on the internet;
does someone know any equivalents for sale on a website he would recommend?
