ONKYO M-504 STEREO POWER AMPLIFIER.Tested, works well, sounds great, nice cosmetics.

This auction is for an Onkyo Integra M-504 amplifier! This powered up without issue when I plugged it in, and the previous owner said it was working fine when he stuck it in his attic a few years ago. I dont have a preamp of any kind to test with, unfortunately, so powering it up was as far as I was able to go, so you could consider other aspects of this amplifier as being untested, being sold as is. Im selling this as functioning because it powered up so easily, but again, I havent hooked it up to a sound system. It does have a few scrapes on the sides (I took closeups of all sides), and a ding on the top where something was placed on top of it. If you are interested in purchasing, Im open to running any suggested tests. I offer multiple ways to ship; please be sure to check out the options so you can select whatever is cheapest - or best - for you! Being sold as is, where is, no warranty expressed or implied. Will combine shipping on multiple items whenever possible. Feel free to email with any questions! All of my items are kept in a smoke-free and hypoallergenic-pet home. I offer shipping via USPS and UPS. I do not charge extra for handling, and I only charge for shipping whatever the eBay shipping calculator designates. If you would like your package insured, please let me know, or add it to your shipping costs when totaling!

If you know, you know. If not, look them up.....Offered for your purchasing pleasure is a matching set of ONKYO Integra components including the MASSIVE M-504 power amplifier with huge dual VU meters and the P-304 pre-amplifier! First and foremost, both work and are ready to use as pictured. TONS OF POWER. Video available. Read on for details: Maintenance consisted of the following:Amp chassis was dustered, was already super clean. See pic.No other cleaning done and no repairs made.The bad:Lighting on amplifier right side VU meter needs attention. Several times when turned on, the lamps would not illuminate. No apparent issues seen inside the chassis. A couple of taps on the outside would bring it on, but only one of the two lamps work. Probably easiest to change out all lamps on both sides, or run as is. Last few times we turned the amp on, the right side lit up immediately. Meter works no problem. See pics.Pre-amp is missing a REC selector knob. Replace one or both, or leave as is.Some spotting on pre-amp. Hard to notice unless youre really up close. We did a general cleaning only, some polishing may remove it. See pics.Testing/The Good:Amp has super clean and clear signal on all four speaker outputs.Tuner, CD and phono inputs are guaranteed working good, no other testing done.Both VU meters work well, bar the aforementioned lighting issue.Rosewood finish end caps are beautiful on both pieces, with some minor scratches on one panel on the amp. See pics. Please ask questions! Remember, this set weighs a ton and will not be easy to ship. Hence the charge. They will be shipped separately. Each will be secured in first box and then boxed again. Both will be insured.

Genuine Vintage Onkyo Super Servo Interconnect Cable.

Item will be shipped and packaged well, I have 100% feedback, so please leave good feedback and Ill do the same.
