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.
Jack's Photos: The Blonder-Tongue Audio Baton
Links, down the bottom.

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

The Blonder-Tongue Audio Baton is my next project, it will takes maybe one year to finish it, still working out how to add a modern trick to it...all the best to everybody
