I have a habit of checking here anyway .
I haven't tinkered with my machines for about a year , il wait for something to break again and that will get me going .
I got a 30 year old TVR , there's way more to go wrong than a portable
Il see if i can spot a module , i have never really looked into that , but u should see if you really need it in practice . Another way to lower current draw is by restriction , if you look at an amp meter while using your machine its going to drop while cleaning , fluctuate , so its not like a steady 15amps the whole time .
Personally i would try it and see if your plug gets warm , if not no problems . As long as your plug connections and general wiring are fresh i dont think you'll notice any issue .
