You're still a cool looking dude, and your waistline clearly shows you are a man well capable of appreciating the finer points of life. No man can be complete without that. Life is far too short and valuable to waste on worrying about cholesterol, lipides and such like forms of distortion.

Just slew it all the way, is what I say. If you take out the coffeine from coffee, then what the hell is left to drink, other than coloured tap water, right?

Don't you pay any attention to these modern whizz bang kids, heck, they even have sex via the Internet. And they worry about my cholesterol? Sheesh ....
I said changes .....

Anyway i gave no opinion, just my observation and sex via internet is safe sex , the PC gets it ........
I found his Ampex comments interesting, obvious fond memories ........

How true . I was born on the same day as Cervantes .

Why am I not surprised?

But seriously, and I'm guessing now, I would think that in these all digital days, things like octave graphic equalizer would be rare birds.

Years ago, they were down to being cheap'n'cheerful toys, in fact mostly misused, because those who owned them had neither the knowledge, nor the need to apply proper measurements to make full use of them.

Today, I understand many new receivers have full on-board calibration facilities and are supplied with measuring microphones, anbling a formally more harmonious blending in of audio gear. Haven't tried it, so I have no idea whether it works and how.

Which makes octave, and even third octave, equilizers vintage gear. That should make them relatively cheap to buy, and gives one much leeway in rebuilding them, given that most are op amp based.

In your case, I would imagine that perhaps a parametric equalizer would be a better proposition. I should still have a schematic somewhere, I'll look it up. Its key benefit is that instead of awful cheap pots you can at least install something decent, like Alps Blue, or some such. It probably won't be too cheap, but it could be really well done, what with all those op amps you seem to grow in your garden.

From how I have understood this we do better just to notch out the peak and throw it away . The analogy I would strike is two colour process of the 1920's . The eye will put back the colour . I am guessing that is what happens here ? It is so nice not to have to chop down all the mountains and fill all the valley's . My friend supposed this and it seems correct ?

100 % agree about the step beyond what was asked . My assumption is a correct technique up to 200 Hz ?

I said it for fun ( truly , sort of Methuselah me ) . Cervantes perhaps marks the beginning of the enlightenment ? To be even then seeing the rustic cavalier as we do !

Good circuit, but where do the groundside electrons go? And no Mingford or Bayshag components, which are essential for any decent audio.

No. Spoof I can cope with, but spoof masquerading as reality is too much for me. When I watch a film/TV I like to know in advance whether it is comedy or drama. The exception is politics, which I know includes both.
