I just repaired a power supply for an infra red lamp used in a material guage, it had failed in a very unusual manner, the psu is placed in an under floor cable run, condensation is an issue.
The back of the TO3 transistor case has rusted right through and got to the die, the device is open so maybe its even rusted through the cat whisker to the pins.
Is there a stainless steel version of the 2n3055 available?
For now the replacement device is splodged in red oxide.
