Cassette Regret
The shop I work at mostly repairs computers, phones, and tablets, but we do occasionally get asked to work on other electronic devices (e.g., audio equipment). This was the case this one particular afternoon, when a lady brought in a new-looking cassette tape player (bear in mind, also that this is recent, so these are getting a bit harder to find, as many local appliance stores have long stopped selling them). The manager served her, but the conversation went something like this:
Customer: “I have this tape player, as I have a lot of old tapes which I want to play. I bought it online from the USA and paid good money for it, but I can’t get it to work. I plugged it in, but just heard a pop, and it won’t do anything.
My boss and I can already see where this is going. To understand what happens next, it’s worth remembering the two big differences between the electrical system in the USA and Australia. First, in the USA, the pins on the mains plugs are straight, but in Australia, they are at a 45-degree angle, so an appliance with a USA plug won’t fit into the mains here. Second, the voltage is higher: 120V in the USA and 240V in Australia.
Now, this doesn’t mean that it’s impossible to run appliances made for the USA market here. You can buy step-down transformers with USA outlet plugs from many electronics stores (including one that is only a block away from our shop) and online, but unfortunately, that’s not what this customer did.
Manager: “Okay, so did you use an adapter or transformer to plug it in here?”
Customer: “No, I just plugged it straight in. It didn’t fit very well into the plug, but we bent the pins with pliers, and it went in.”
Manager: “Um… okay. One of our technicians will have a look at it for you.”
After having more of a look, I can’t emphasise how dangerous this actually was. I could see that the two pins on the mains power plug indeed had marks on them from pliers and had been bent and twisted to force them to fit into an Australian plug (at least if you really forced it) – but they would only go in about half way – just enough to make contact, but not enough to push the plug all the way into the wall. There was a twisted section on the pins, which was still exposed, and there was enough of the plug hanging out of the wall to fit your fingers behind and potentially touch a live pin!
Of course, after opening the appliance up, the main transformer was completely burned out and melted to a crisp, thanks to having twice the rated voltage fed to it. The silver lining here is that the damage was limited to the power supply section, and I was able to repair the device and modify it to make it safely run here in Australia.
If an electrical plug doesn’t fit, don’t twist it and force it. Thankfully, this customer didn’t end up electrocuting themselves or causing an electrical fire. But I do worry that the next person to try this might not be so fortunate.
