Hi,
On the old forum PRR posted a picture of 24vdc supply that was nothing more than a 24vdc wallwart filtered by two 27 ohm resistors and two 4700uF/35v electrolytics. I have the drawing if anyone is interested (I hope Chris doesn't try to sue me for copying it! )
Anyway, this supply works brilliantly in a pair of Pultec clones with Neve outputs and a few passive mixbuses with Neve outputs that I've built so far. What I'm wondering (because I NEED someone to help me with this as I really don't yet know squat about power supplies) is can I use the same wallwart and add, in addition to the filtering, a DC/DC converter to provide 48v phantom as well? I'd really like to stick with the inexpensive wallwart but also have phantom power for some Neve-clone mic preamps.
FWIW the 24vdc wallwart is 400ma output.
Any ideas?
Thanks so much,
Joel
