Title: TAF line filter
Post by: faza on February 02, 2013, 04:32:21 PM: After replacing two thermistors it looks like my line filter is shorted across active and neutral.
Anyone know if a direct replacement is available in Oz.

Maybe check with Mike (Homepin), he may have a better source.

Varistor is across the active and neutral line tabs on the EMI filter.

Do the Jaycar ones share the same footprint size as the originals? That's why I stuck with the Rockby ones as they are almost identical

Thanks for the replies I was after one that would fit identically to the one I've got.
Yeah Nino high current due to the short is destroying the thermistor.

They are plastic cases. The lugs are small and the plastic case melts when you apply too much heat. I like the traditional metal cases. I use these on my restorations and repairs. I'm sure the plastic ones are ok - as they pass Australian standards - but not mine - and I'm fussy when it comes to electrical items and safety.
