A nice Marantz 1090 with the very rare optional rack handles, cleaned & serviced. The bias was set to factory spec as well. There are some small marks on the faceplate and handles, see the pics. As good as the Marantz 1060 is, this model has the extra power the 1060 always seemed to need.

The faceplate was removed, cleaned & polished with Blue Magic. The case was removed & cleaned, dust was blown out from the interior. All knobs and switch covers were removed and cleaned, all potentiometers and switches were cleaned and treated with Deoxit F100L Fader Lube for long term protection. All functions and speaker connections were tested.

"Very good amplifier with clear and deep bass. The loudness is very responsive. I have been using it as a pre amplifier with a Model 250M power amplifier. Amazing sound with my JBL E60."

ALL ITEMS ARE DESCRIBED AS BEST AS POSSIBLE AND DUE TO THE NATURE OF USED ITEMS ALL SALES ARE FINAL.  I am very honest about any issues that exist, just check my feedback. One buyer reviewed me as “Honest, Honest, Honest Seller”. The one recent bad feedback was left by a scammer. I treat buyers like I would expect to be treated. I am a hobbyist that buys items that need help, clean/fix them up, enjoy them for a while and sometimes sell them. I do not work on other people's equipment. If you need someone to service your equipment, I recommend Just Audio in White Marsh, MD.

If you need help hooking up anything you buy from me, just message me and I would be more than happy to assist.

Check out the photos. The photos display exactly what this item is. I would like to guarantee this item. However, too many unprincipled buyers that strip parts and then wanted to return electronics as being defective force me to protect myself from this type of abuse. I will pack well and insure the package during shipping. One recent buyer stated that he thought that his unit could have been dropped from a truck at highway speed and still survived intact. If the shipping cost seems excessive, eBay seems to overestimate shipping costs so I have been offering to refund anything over the actual shipping cost. I tell them the size and weight and they estimate from there.

·  Nothing else, no further warranties or guarantees are implied. This vintage item is being listed and sold AS-IS because of parts swappers, people hooking stuff up wrong and scammers.
