MC 240 Thermistor

[kennyno]

I'm trying to get my mc240 working I'm new to this but I have re caped a few old radios.
I am at the point where I think all I need is a new thermistor for mc 240 to come to life.
I have no idea where to get one or what to ask for except its a thermistor.

Mouser sells a good variety of them. That's where I buy mine.

Thanks damacman could only find one thermistor at Mouser
High Stability High Temperature Thermistors
Is it one size fits all ? I have the schematic but all I see is R56 part # and 79 AT 25*, S1
like I said I'm new at this. Thanks

Here you go. Thermistor can be ordered from Audio Classics or McIntosh.

They're not one size fits all. Rule of thumb is look at fuse size. Its likely a CL80 or a CL90.
I'm sure you can buy it from Mac. It might be slightly more than if you bought from Mouser but it takes the guessing out of it.

McIntosh 144-006, Thermistor rb 144-151 is essentially a CL90.

Call Brian at McIntosh 607-723-3512 or bscott@mcintoshlabs.com.
