Onkyo M-510 Grand Integra

Selling my beloved Onkyo M-510 Amplifier. I still can’t believe I’m willing to let it go as it served me well for 30 years without any issues but it’s time it finds a new home!  I have so much electronics and now since moving to Wisconsin, ( I was a New Yoker my entire life ), that I just don’t use it anymore. Its been well taken care of it’s entire life, always covered when not in use and was opened and cleaned with pressurized air every few years. There’s no cob-webs in this unit. It’s very clean inside and out. It has a few minor scratches and nics from usage and time ( I’ve tried to take pics the best I could ), but overall I’d rate this a solid 8.5/10. Wood very good with a couple of pressure marks on left top rear edge and even smaller on top front left edge. A few minor nic's on front/ top panel but again, very small.  A brief history : I worked at Onkyo for many years during the early 1990’s. An M-510 was sent to a dealer as a favor, was set up to demo but the deal fell through. I had been wanting one since it came out in the mid/ late 80’s. Well, I grabbed it! So I’m the original and only owner and it was purchased at Onkyo while I was working there! More specifically, I worked for the wonderful rep firm Roth Paris Marketing but solely represented Onkyo and basically worked right out of the company located in Ramsey NJ - 200 Williams Drive! I lived in Irvington NY so Onkyo was only about 30 min. from  me. Those were the good ole’ Days!!!!  I was a total Onkyo fanatic! Actually I still collect and sell vintage Japanese audio gear. I currently own over 100 components including all the Onkyo Grand Integra components. If you notice in one of the last pictuers, I’m including more then a dozen pieces of literature - most of which revolve around the M-510. This will include the original owners manual ( which were just paper - copies right out of the box ), schematics if ever necessary, a bunch of fantastic reviews and even an original, made of a thin cardboard, Grand Integra confidential cost sheet! The only book that will not be an original ( I’ll make a color photo copy ), is the ( on bottom) , color Grand Integra brochure. I’m keeping the original for myself. Many more things included here too. I’ll be adding more info but wanted to get this up. Shipping this 140 lbs. monster is challenging. I'm presently looking into this but have found no reliable company. I’m open to suggestions or would even drive a good distance to meet up with a future buyer! Or feel free to meet me at my house for a demo and great conversation! TBD. Also included is the original, roughly 5 foot long, Integra RCA interconnect and in very good condition! And four ( 4 ) OEM Lamps should they ever go out. Serial # 7004000087. I have not found a shipping solution that I can trust. As of now, the amp would be local pickup or as stated earlier, I will drive a good distance to deliver. Thanks.
