Subject: [Amps] Alpha 89 thermistor question

<I have a faithful Alpha 89 which has served well over the past 25 or so
<years, except for one annoying problem - it randomly gives a 'temperature'
<fault for no apparent reason, requiring the 3 min reset. The control board
<has a 'temperature' input but no thermistor is indicated on the schematic or
<on the parts list.
<Does anyone know where the temperature sensor resides or how it works?

<Many thanks for any help

##  well, you could run it by Alpha, since you may well have to replace it anyway.
