An excellent condition 1.080.391-11 IC Decoder Card for Studer A80 and A80R model reel to reel tape recorders.  This was pulled from a working system and inspected.  The two 22uF 40V Frako Electrolytic Caps have been upgraded to Vishay 50V caps.  I've used and trusted these exact caps in my personal machine for years, this card should be good to go for another 40+ years.  Sold as-is
