Could not find a forum. Found out though the brand is phonics digital. I have searched all over the place. I have emailed them to no avail. It has to be out there somewhere. PD-393

Yes and I was hoping yall could help me find a decent picture or manual.

I recently found an amp that used to belong to my brother. It is a PD-393. The markings for the terminals as well as the adjustment knobs are gone. I am looking for a manual so I can find out if it still works. I have briefly looked through the forums and couldn't find anything.
