Otari cards in stock:


These are new old stock from a factory buyout. The two PB9A266 cards are the only used cards on the page, all others are new in original Otari packaging. As of 9/27/2013, there were 116 new cards and 2 used cards in stock. After selling some individual cards, the cards were recounted, and as of 12/11/2013, there are 97 new cards remaining and no used cards.

Otari cards are very difficult to identify, because they don't have anything useful written on them, and often are referred to by one name (something totally nondescript and meaningless), but have that name or even another printed on the card. Sometimes they are referred to by the first with no mention of it on the card, where the card only has the second, so someone needing a replacement for the card is going to refer to it by the second name, not even knowing the first and "real" name that Otari themselves would call it by. Very often, one number (the correct part number Otari would refer to it as) is written on the bag, and the "PB9Axxxxx" PCB number is the only thing written on the board, so the minute you take it out of the bag, you no longer know what part it is.

For this reason, I have tried to list both names if they are known to me, and where they were written. This might put the cards out of the intended numerical order on this page, but you can text search this page to find the part number or part of it.

As noted above, some of these have markings on them, but are packed in original Otari factory packaging and have another part number written or tagged on the bag, so I have noted that, too.

Giving the cards markings like "MX5050 MKIII CPU card" would have made too much sense, so Otari gave them catchy names like "PB9A870C".

If a field is left blank, such as the application, the information is not known. Web searching every single part number only turned up names for a few of the cards. By all means, if you know what a card is for and I don't have it listed, please let me know.

These are priced below, mostly at $30/each for the larger cards and $20/each for the smaller cards and modules, but if some audio tech would like to stock up on the last of the new Otari cards, then I will sell the entire lot (two large boxes) for $375 plus shipping anywhere in the world.
