Buyer beware.
Hi peeps..... Long time no post
 . Recently I bought some AD603 I.F amps. Nothing wrong with that you say..... but a word of "heads up". They are SOIC "smd" version. The pins are oxidised, and will not solder as you expect. I was caught out when soldering. Fortunately they cleaned with a Fibreglass pen.. but the "ground pin 6" was floating, obviously causing a DC issue. Other than that.... a very useful animal.
