I've made a passive Mid Range Equalizer
The filter circuit is from the classic Pultec MEQ-5 with some more frequencies. Input and output stages are THAT 1246 / 1646.
The filter is driven by a DOA and the output buffered by a NE5534 that also feeds the input of the 1646.
The difference to other solid state circuits maybe is that I drive the filter circuit quite hot through the DOA and there's not so much gain from the output buffer. Does it sound different? I don't know
Here are some pictures that I made while working on the unit:
