I use Ametherm NTC Thermistors. I use their part
number SL32 10015 that has 10 ohms of initial
resistance and is rated for 15 amps maximum.
Been using them for 3 years in a Swan Mark 1(two
3-400Z) and a Heathkit Warrior HA-10(four 811A). So
far so good.
Here is the Web Site. They have been very geneorus
with their samples.
