Denon Pre Amp no sound


Dealing with an issue in a recent post I bought a inexpensive pre amp to get me by until my equipment is repaired. I bought a PRA 1500 pre amp off of Ebay to mate up with my Denon POA 1500 amp. Anyway, of course, it came dorked up. One of the CD rca plugs were broken, but more importantly the small red light on the volume dial is not lit and the pre produces no sound. When something like this occurs is there one or two issues that typically cause the damage? And did I learn something from this experience, no more equip off of Ebay (again). I look forward to you thoughts. Thanks much, Dave

Take the case off and look inside, both on top and bottom of circuit board. I was once fooled by a Kenwood 917 tuner which had them in both locations. This does not require advanced skills or tools beyond a screwdriver or allen wrench.
Stanwal, good call. Yes, there is an internal fuse that looks fine. I also discovered that a thin cable from the inside of the volume knob was broken, looks like it just wore out from years of use. Hopefully a simple soder project with a piece of new wire. To all, thanks. I'll follow up after the repair is made. Dave
