I'm selling one pair of LME49990 op amps mounted as duals in Cimarron Tech Brown Dog adapters, ready to plug into the sockets.
I had been using them in the U1/U2 positions in an Eastern Electric MiniMax Plus DAC. They have a couple hundred hours on them. These op amps in the EE DACs run in both SS and tube mode, whereas the U6/U7 are only used in SS mode.
I will include one single mounted LME49990 as well, which I was using in the U6/U7 positions. I had a second one but I dropped it and stepped on it! (A replacement is $23 inc. shipping from Cimarron)
These are great sounding op-amps; very fast, detailed and clean. My favorite of the non-discrete op amps. Needless to say, they also can be used in many other types of gear with socketed op amps.
Cimarron sells the pair of duals for $80 inc. shipping, and the one single costs $17 more.
