I have been given ann Eva 1 LDR remote control preamp, single RCA inputs and outputs. But it came without a wall wart power supply.
Anyone know what voltage and current rating the PS should be?
Also, which is the input and output pair?
Guessing inputs on the outer side, outputs towards the middle of the back of the enclosure.
Hopefully the balance is okay. LDRs tend to drift with time, it has been my experience.
Thx in advance for any assistance.
Cheers

Is there is pic of the thing? Do you have a pic of the inside so we can see the PCB? Is Eva the name of the manufacturer, or who made it?
If you google diy paradise with Eva 1 the product shows up with image but I looked inside and there is no helpful info.
The site seems abandoned. It was run by a guy named Yeo.
If Yeo still frequents this site then maybe I have a chance…

A pic of a PCB can be helpful to us a lot of the time. Some here know how to reverse engineer some things from no more than a pic. Only way to know for sure is to see one.
Also, a pic of this one shows a 12v power supply. Don't know which pin on the connector is + or - though. https://www.audioasylumtrader.com/c...d-LDR/Passive-Preamp-Bonus-Power-Supply/74274 That said, the claims in the ad are silly wrong. LDRs are not that good for audio preamps, they are too nonlinear. Better for switching signals in guitar amps.

Thanks for that. Already aware of its 12v status.
Eva 1 is quite different, single inputs and outputs. On what's left of the DIY paradise website, his initial efforts with LDR showed a 5v PS, which is why Im a little nervous about what to plug in. I have both. Will post images of the innards but I don't think they will be any help.
