PSU for DOD R-870

Hi all,

I recently picked up an old S/H DOD R-R870. The guy who sold it didn´t have the power supply. There´s no info on the backplate. Anyone know what voltage, AC/DC the unit needs ??

Thanks in advance

First thing I would do is read what the wall wart says on it.

Some of the old DOD stuff had AC inputs for power (at around 24v, if I remember right).

no wallwart here...nice knobs a plenty

ac=24v?

like i said, i'll be happy to open the bugger up and take some readings

if someone can walk me through the process

so i don't destroy the unit or myself you see

Don't bother opening it up. Jens seems to think there is an external power supply for the thing.

Sounds like your's just plugs into the wall.

r0ck1r0ck2, thanks for your karma belief but as tiny suspects mine is supposed to have a wall wart. It has a 2.5mm or 3.5 mini tele female connection.Tried some diffrent wall warts but no one came close to 24v. Heck, I might even be broken.

Do you have a camera and a screw driver?

Here are the pictures. Thanks for helping me out.

The upperleft shot is where I think all electricty things are happening so I focused on that area. Otherwise please look at the overview and tell me where I should have focused..

Thanks again.

Feed it DC at something less than the voltage rating of the big yellow capacitor in the corner.

If it's rated for more than 12V - you might want to start at about 12VDC.

If that gives you enough headroom, call it good.

If not, we'll have to take a closer look at the black "D" shaped package closest to the big yellow capacitor.

tINY & r1r2. Thanks alot for your help. Tomorrow I´ll pick up a DC adapter and try tINY´s way. Hopefully, and surely this will work just fine. If not I´ll come back with another close up.

Thank you so much again.
