My faithful mod'd halogen TO has finally given up the ghost after serving faithfully for the past three years or so. It sets off the circuit breaker every time it's plugged in, even without the element switched on.
Lucky I still have the old solid event TO as a spare so I used that today to roast up a couple of kilo's of Ethiopian. I forgot how bad the lag is compared to the halogen, and also the temp ramp capability is slightly less.
Anyway, I'll pull it apart and take a look inside. If nothing obvious it's going to the local appliance repair man to see what he can do.
