been searching through the archives and can't seem to find an answer. also i'm very new to building power supplies and will need someone to hold my hand through this.
i don't want to keep purchasing 9v batts and am not sure i want to go the route of internal rechargeables...
so has anyone made/used an external power source for the Denecke AD-20 (Zefiro Inbox) and how did you do it?

I haven't done it because I don't own one, Simp, but given the broad voltage range supported (5.5v - 25v) and the minimal current draw (50mA), it'll be a breeze to put together a compact, long-lasting external power source.
Personally, I think NiMH 9.6v RC batts would be a great way to go. Even a small 1000 mAH RC batt will give you ~20 theoretical hours of recording time.
There are some pretty good instructions with pics in the Archival Forum:

The differences for your application will be:
[1] no real need to wire two batts in parallel since you'll get such ridiculously long run-time off a single battery
[2] instead of the adaptaplug connector, you'll use whatever connector and pinout the AD20 requires (mono 3.5mm male connector, tip (+), ring (-) if memory serves)
Curious to see if anyone's done this for the AD20 before... :)

I used to have an AD-20 a couple of years ago. I powered it and my D8 from one 6v 4.5Ah SLA. I didn't build this system...the SLA was purchased from Cascade Media (via Pro Digital)....and I had the cable (3 pin mini xlr -> 3.5mm + Sony proprietary plug) made by Masterpiece AV if I remember correctly. I never tested it to see how long it would power both for. The longest I ever ran continuously for was ~ 4 hrs.
ymmv
