The 9VAC power supply for a two-prong VIC-20 is rated between 2-3A.

The 9VAC line on a DIN style power supply is rated for 1A.

A few years ago some people on the Denial forum made practical tests to
see how far you get on 1A. I believe the VIC-20 will start, but you should
watch out from using peripherals that would draw power, in particular a
tape recorder.

However if you come across a standard 9VAC power source that is rated to
deliver at least 2A, it should be possible to use with a two-prong VIC.
