Preamplifier Onkyo P-304 Stereo Amplifier (1987-97)Excellent condition. Tested, works greatSome small scratchesPlease see pictures for detailes.

Onkyo Integra P-304 Stereo Preamplifier Unit shows cosmetic wear but has been tested and is in good working condition. The only particular issue I came across is some scratchiness in the balance knob. You usually have to find a bit of a sweet spot and it it tends to cut out if turned all the way to the left. Most likely cleared up with contact cleaner, but I have not opened this unit to investigate. Previous owner scratched their information into the back of the unit and has been covered with electric tape. I also currently have an auction for an Onkyo Integra M-504 Stereo Power Amplifierif interested. Package weighs approximately 20lbs and cost of shipping varies by buyer location. Free Local Pickup can also be made available. Package will be insured for final amount and require signature at delivery.

Unit turns on not fully tested has some dents on top of the unit see pictures

See photos for cosmetic condition. Comes with box and manual. Missing panel piece in the left side. One piece of panel is also coming up but can be attached

ONKYO INTEGRA P-304 STEREO PREAMPLIFIER PRE AMP Working, READ description ! Nice cosmetic condition, some normal wear and light scratches on the metal top plate, the faux wood side panels have normal wear and a few scratches, much nicer condition than most that come up for sale. This amp was in a system and is tested and working. That being said I took it apart and it was pretty dusty, I cleaned the boards and got it cleaned up nice. I would assume that due to age that you may want to consider doing some further work to it. Again it is tested and working, but I am selling it AS-IS due to age so please take that into consideration, as the price reflects this as well.
