Or perhaps the problem is counterfeiting? (Re-branding after the fact.) Appears to be rather common for certain numbers. Goodness knows. Never trust Indians ! The company making them was MOSPEC. Profusion briefly distributed them in the UK ( in good faith no doubt ) but have withdrawn the line. Graham |

The ultimate performance from a true original 5532 or 5534 is influenced too by pole-zero compensation around the feedback. Neve wrote an internal application note on how to get the best results. Sorry to dig up an old thread, but what did this Neve internal application note say? If you have trouble, make the feedback cap bigger? ulysses |

parallel with the feedback R. Graham This is for lower than 10K feedback resistor? If so, what for 10K feedback resistor? Thanks |
