I have NOS genuine Analog Devices AD745JN available (8-pin DIP). They are excellent for replacing the LT1028 in ADCOM GFP-565 preamplifier phono stage upgrade (along with required resistor and capacitor changes). These were sourced from an authorized USA distributor and have been long out of production. Total of 11 available (1997 datecode). $6 each plus First Class mail and padded envelope. PayPal with transaction fee added. Sells and ships to USA residents only. Will consider a trade for Maxim MAX420cpa opamps.
