Q re. Northernlightx PSU....

[gavgomad]

Hey all,

As I'm finally getting my 6582 built (ie. need supply to start testing!), and as I need to include a -5V rail for the "to-be-incorporated" 3372 Xpander filters (x8!), I was wondering how difficult it would be to simply add a 7905 -5V regulator on to the circuit?

My thought was to simply add a similar circuit to that used to for the +5v and +9v circuits, but I doubt we'd need to add a heat dissipation resistor, as I don't believe that even 8x 3372's would draw that much current.... Anyone see any probs with this idea? Are we going to destabilize the whole PSU by adding another rail? I think that with a little stretching of the board, the new rail could be grafted in below the power diodes....
