Hi All.
As part of the crossover rebuild of my Mordaunt Short MS 45Ti Loudspeakers I'm looking to replace the 2 Thermistors, which might be Varistors.
As it's been indicated earlier 40 year old Thermistors can become problematic.
Each crossover contains two Thermistors, each of different value.
Thermistor 1 is marked "MEXICO -35 805D"
Thermistor 2 is marked "MEXICO -070 802C"
I haven't been able to track down s supplier or find any technical specs.
The replacements needn't be identical as long as they function with the same values.
Element 14 might have something suitable but their website seems to be set up for those who know what they're ordering.

I couldn't find anything online regarding these.
thanks
Cliff

Likely a Littlefuse series. The symbol is commonly seen on ebay PTC parts, along with Mexico, as well as on seller websites like digikey for Littlefuse parts, even though the Littlefuse datasheets show an LF symbol.
The 070 is likely 700mA hold. The 35 may be 3.5A hold.
