toroidal transformers

[breezer]

lost another "electronic transformer" this evening. I think this one must have been 6 years old so "its done well" however I am of the old school and of the opinion transformers should last for years and years.

I know this was an electronic transformer, so not a true transformer, and its about the longest one has lasted for, so i am contemplating changing to torodial transfomers that TLC supply.

my question is has anyone here tried the ones from TLC or a different supplier and if so what did you think to them.

Its no iltreatment, none have were / are in limited space or overrated, they just seem to fail as and when.

Have had just as many of each type fail.

One piece of advice from experience using toroidials at work on dimmers was we found we had to uprate the toroidials output by three times ie from 250va to 750va in order to stop the primary windings failing due to the choppy waveform output of the dimmers this would even occur on "inductive load" dimmers.

oh.

no what i was expecting, but thanks very much, perhaps i will buy 1 and see what happens
