Equalizer looks very good on outside, as well as inside. Ive had cover off, and I couldnt find anything that had come disconnected, and nothing looks burned up. Had it hooked up to series II speakers - it may change bass tone a little, but Im honestly not sure. Red light does not come on when plugged in. Missing treble knob. Excellent candidate for rebuild.

Bose 901 Series III Active Equalizer w/European plug, serviced & tested. It works in the U.S., adapter included. All controls were cleaned with Deoxit D100L, tested good. 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 peoples 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. Shipping damage has not been an issue for any of my items for many years because of the care I take packing. 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. · I video record the unit working, as well as the process of both packing and shipping so that there is concrete evidence that the item I sent is what was listed. I will also have video recordings of returns being opened. I will not only take this evidence to eBay but I will take legal action as Mail Fraud is a Federal offense.
