IC Clones, PrecisionSpeck Guarantee

[sharky]

I find many variants in IC's with similar names like the various Pulse Induction ckts, be careful with the prefix like NE5534A,B,C,CP etc etc

u need to use the guarenteed noise 'A' prefix one as the remainder are not noise or other precision guaranteed..the IC's are similar to ur variants of the PI circuits which are clones to each other with just a swap of the LM318 or Ne5534 may be some times Lm709, there is no point in choosing NE5534 if u dont see to the Suffix A ie NE5534A...

Also make sure you be using the Phillips brand as seems to be the better one to work for some reason. Have tried others and dont seem to perform the same.
