I just discovered yesterday that a new Commodore 64 power supply exists, and is shipped by a company in Poland.
It has the same 7-pin DIN plug as the original “brick” power supply with a 5VDC rail and 9VAC rail.
Should be a good investment for people who fear that a 30 year old C64 brick might fail and damage their SID chips in their MIDIbox SID / MB-6582.
Also don’t forget Altitudes idea of using high efficiency RECOM switching regulators in the PSU circuit of the MB-6582 / MIDIbox SID, which allows you to use a common single rail DC power supply.
