PSU combination

MIDIbox SID

Hello,

I’ve used PSU option B for my MB6582, because i’m using the 8580 and the 6581 together.

But is there also an easy way to use an 9VDC adaptor, for when i decide to use only 8580’s?

Is it sufficient to connect an adaptor connector to ground and 9V at J4?

Thanx

actualy, i’m asking this because i’d like to use a lighter version of the very heavy C64 power supply for when i want to go gigging with only 8580’s…
