Very professional, I love it always in rack mount.

The BBC AM1/11 equalizer and or Blonder Tongue Audio Baton schematic IIRC appeared in a quite old engineering publication. I have been trying to find this on my server, or find the schematic I possibly re-drew of it from that old mag and compare.

No luck so far, but I think it is the same, the tip-off is the last (lower) stage, dual purpose highest and lowest bands, 10240 and 40 Hz.

Great topic, so many good information and designs to do more thinking about!

Google found a poor scan, first hit.

Links, down the bottom.

The BBC unit added 220V power and proper radio-network output stage.
