    HI, I recently purchased a mine detector AN/prs-8 and can't find any manuals or schematics. Do you have any ideas where I can get these?
    Thanks. Jay Dee

        Your are correct in your information, Mike!

        Hi, Mike. Thanks a lot for your response. Yes, I believe that the 156-PMD is my An/PRS-8. Everything seems to fit and the description fits what littlebits on information I have already found.
        I have been spending hours looking on the internet for information. I am using only 4 "C" cells but will now put in 5. I did sense one component warm to the touch when I tried to demonstrate howit wassupposed to work to my grandson. I will check the battery current draw to see if it seems too much. I would like to look up the Maintenance Manual MM/156-PMD to see if I could check it out further and get some readings on the test points I saw.
        Mike, I appreciate your help very much. Are you a radio amateur by any chance? My US call is KK6OZ. You can look me up on QRZ.com
        In His care, Jay Dee
