Thermistors suitable for radios?

[boater sam]

I have a couple of radios with series heater chains that need new thermistors. One set is a Bush VHF90 which has been on the bench for ages and now is all working except the thermistor which is O/C
Does anyone know what the spec is of these?
I have been offered some old stock RS T H 6, would these be OK?

Its a CZ1 type - see attached document for details of its characteristics.

Paul Stenning also did an Excel calculator to help with dropper calculations should you choose to use some other method other than a thermistor - http://www.vintage-radio.com/download/vi...ations.zip

The Mullard Maintenance Manual lists the VA1005 (trade name "Varite" rather than just "thermistor"!) as a replacement if you can't find a genuine good CZ1...
