content: Last week we had a Denon hi-fi amplifier come in with the fault; "smoke came out then stopped working".Here's the cause. He was hiding right under the main filter capacitors. When the owner switched the amplifier on, BAM, full +/- DC rails across the little critter!Luckily (but not for him!), the only real damage was some burnt PCB traces. You do have to take the whole amp apart to get the main board out though.

content: Yes, part of the solder mask did end up more attached the the Gecko than the PCB.

Low Tension heater supply leads however,he got the wrong pair and found 120 Volt DC, H.T. High Tensionboy did he jump... said he saw stars before his eyes.

content: I get this quite regularly on air conditioning systems that I service. Normally they just short out the mains and take a fuse, cap or pcb track out, all of which or easy to be repaired, unfortunately the lizards can´t be repaired.I did have an incident last year where a lizard stepped across the mains filter cap, the fuse and main processor on the pcb. There was nothing left of the lizard at all, other than a skeleton, the cpu was fried as well as a few miscellaneous components. The fuse was alright though. All in it cost around 2.000€ worth of damage.They seem to prefer inverter systems for some reason.

content: Haha, I usually don't mind them in the house, seems to keep other bug infestations at bay like mozzies, cat always manages to find a few at floor level and out in the yard to bring inside though.
