Hi -- I'm a rank beginner, and probably in over my head, but that never stopped me before...
Let's say I had to replace the power section from this schematic:
http://recordinghacks.com/images/mic_extras/cad/E300-schematic.png
(As I understand things, it uses a couple of 9v batteries (NiMH or NiCad) as a backup to handle higher current draws than phantom supplies can often handle. It can also run without phantom.)
Would it be all that difficult to build an external power supply that took 120VAC mains and provided stable/clean/adequate 9VDC and 18VDC for the V9 and V18 points, and let me skip recreating the whole power section, batteries, etc?
I just wanted to figure out if such a project was a matter of finding well-known schematics on the web, ordering some parts, and going for it, or if a 9v/18v power supply is an unusual configuration and would require custom designing, etc etc. Meaning, if I just need a transformer or two and some filter capacitors, I'm all over it, but I'm not savvy enough to design my own circuit, really.
(I'm assuming that grabbing a 9v and an 18v wall wart and hacking those together is a stupid idea.)
Thanks for any ideas!
