It is rare to find a 504/304 combo in such good condition, which is why I paid a premium for it. I have fully serviced both units and is now offered for sale. I installed new Gold plated RCA jacks on the P-304, and serviced all knobs/ pots. Everything works great. On the M-504, the bulbs were fine, but they die over time. So I installed two Straw-hat LEDs next to them which should outlive the incandescent bulbs. The unit was properly biased, and the meters calibrated. They were both off when I received the unit. Both units have custom Ash grain side panels in a dark Jamoca color. I personally chose the board such that the grain pattern continues from the pre-amp to the power amp. Both units (given their age are not perfect) but in super excellent condition. Those green meters are a joy to look at. I took several photos to help you see the value of this combo.

The left light is burned out, but everything else works perfect and the sound is incredible crisp and clear and powerful. Auction for the amplifier only not the Blu-ray player on top of it. I think it's 30 years old.

Up for auction is a used Onkyo Integra M-504 Power Amplifier. I am the second owner. I am selling this one due to having another M-504 and various other Onkyo m series amps. The amp itself is in excellent condition as seen in the photos. Has a minimal light scratches and dings. Still works and performs great. I am sorry I do not have the original box or manual. I custom made solid oak wood panels for it. I am also including the factory OEM side panels in the auction. I installed new 5 way binding posts to replace the awful factory posts as I do with all my Onkyo amps. I had to make a custom inside panel for it to work right. All the posts work great on both sets of speakers. I am also including 6 new Green LED replacement lights. As seen in the pictures the lamps will need to be eventually replaced. They are dimming some and one I believe is burned out. I can’t remember if the amp takes 4 or 6 lamps. Thus, I am including 6 in the auction. I will promise and guarantee the amplifier will be packed and shipped correctly. I have fitted foam and foam molding I will secure the amp in. Every amp I have sold on eBay and other sites have NEVER had any damages or issues during shipping. I will make sure the Amplifier is fully insured for auctions end value in case of unforeseen damage. Comes from a non smoking environment as well. Please do not bid if you don’t plan on paying. Please try to pay after auctions end. If there are any issues with payment , or you need more time, please notify me before end of auction. I usually ship out within 2 days. Please feel free to email me with any questions you have. Thanks so much!!! Jim

Audiophile grade ONKYO Integra M-504 Stereo Audio Power Amplifier Bench Professionally Tested Excellent Condition. I took this to Classic Audio Repair to be bench tested and inspected prior to listing on 7/16/24. See the pictures for the receipt and results. Overall great cosmetic condition as well. There are three very small scratches on the housing. One is on the wood grain and two are top front. See the pictures for the cosmetic condition. I have taken many pictures. Comes in the original box and styrofoam. Does not have the original owner manual, but I have printed a owners manual and service manual to be included with the amplifier….. At time of listing I also am listing a ONKYO INTEGRA P-304 Preamplifier and a ONKYO INTEGRA EQ-35 Equalizer. Both have also been BENCH TESTED. I also will be listing some other ONKYO pieces such as a CD changer, tape deck, AM/FM tuner, and a record player in the next few days. Thanks for looking and contact me with any questions. Please message me for an accurate shipping quote as it is a big heavy box and eBay has a tendency to quote the shipping costs a little higher than what it should. This will be shipped insured at the buyers cost. The handling cost is covering the shipping insurance cost.
