This auction is for one piece of a vintage op-amp, the P65AU from Philbrick Associates, the company that first commercialized the operational amplifier. This item is from the era when the legendary Bob Pease worked at Philbrick. It's one of the first solid-state op-amps; at the time I bought it back in the '60s, Philbrick was still making the K2W tube type op-amp. The last time I fired this up was 50 years ago, but I believe it is still fully functional. In any case it is a valuable addition to any electronics collection. It's complete in the original box with the original data sheets enclosed, as shown in the photos.
Condition:
Used: An item that has been used previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a floor model or store return that has been used. See the seller’s listing for full details and description of any imperfections. ...
