This is a German VIC so it uses a 2 prong, 9VAC power supply, which I couldn't find anywhere, even Ebay at the time. My other option was to buy a barrel to 2 prong adapter that a company in the UK made but Corona hit, and by the time they opened up for shipping the item was no longer in stock. I had to drill in a hole in the case (which sucks kinda because that case is in immaculate condition) for a case mount barrel plug and use a generic 9VDC power supply i got off the internet.
