Onkyo Integra M-503 Power Amplifier and Integra P-304 Pre-Amplifier.

ONKYO Integra M-504 Amplifier & P-304 Preamplifier. Because this is a vintage audio unit it is sold as-is no returns. You are more than welcome to inspect and audition upon pickup to verify it is in good working order. This classic amplifier and preamplifier set is in spectacular condition both functionally and cosmetically. I've spent $400 in the last two years having both fully serviced, cleaned, and maintained. This includes LEDs added to the VU meters, parts replacements, board repair, and protection circuit replaced with new relays. The amp is fully within spec and bias as you can see in the pictures. Sound quality and performance are outstanding. Specifications • Power output: 165 watts per channel into 8? (stereo) • Frequency response: 1Hz to 100kHz • Total harmonic distortion: 0.003% • Damping factor: 140 • Input sensitivity: 1V • Signal to noise ratio: 120dB

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.
