For sale here are used, tested Harris 911 op amps. These are the exact same part as the MCI 2001 and Harrison 3500 opamps, and used in the MCI 400 series consoles, MCI JH-110A tape machines, and Harrison 2824 and 3232 consoles. (In fact, the original 2001's used by MCI in Florida were Harris 911's with MCI's custom part number stamped on them.) These particular opamps were designed for +/- 24 volt supply rails and replacement parts have always been very difficult to source.

The appearance differs slightly from part to part and on some of these, the leads are cut down to 1/4 or so fit in a IC socket. Some are marked 3500 and some have a green test dot painted on the top. I tested them all on a test jig in my shop, checking supply current, signal/noise, frequency response, and stability. I'm very confident that these IC's are good working parts but we cannot guarantee them after they leave our premises due to the chance of a buyer unknowingly installing them in a malfunctioning circuit, installing them incorrectly, or otherwise damaging them in some way.

Even though these are small lightweight parts we have specified priority mail for international shipping. In recent years we have experienced many lost items when shipping overseas with first class mail and small flat rate box services and are cannot use these services for purchases of $50 or more. For some destination countries we can send 1 or 2 of these via first class mail but for this option please contact us before buying. Thanks for understanding.

We're in the process of listing many other MCI opamps and tape deck / console parts; please check our other auctions for all kinds of other audio parts and equipment. And please have a look at our feedback. We're proud of our reputation on ebay, and we take good care of our buyers.
