OPA2604AP Burr-Brown Op-Amp Set of 2 [Tested and Working]

Two OPA2604AP dual operational amplifiers for audio from Burr-Brown are offered for sale. The lot number is "7AW445B".

These were purchased new about 15 years ago and have been stored unused.

As shown in the photos, the pins have discolored to a brownish hue due to aging, but I have confirmed that there are no issues with sound quality by installing them in the IC sockets of my amplifier and playing music for about an hour.

At that time, I used a tool called "pin sorotta" to straighten the IC pins vertically to facilitate smooth insertion and removal from the sockets. The pins are splayed outwards when new, but the pins on these items are vertical.

Please be aware that these are not strictly "unused" as they were powered on for the purpose of confirming operation.

If you need more than 2, please let me know the desired quantity in the comments, and I will relist them with the quantity and price (@1000 yen x quantity).

Shipping will be via Yu-Packet Post Mini from Kanagawa Prefecture.

Thank you.
