Hold on here, just what is the issue? there is an amplifier,
it applies a frequency response curve. That is that. Do you
think the EQ network is faulty or what?

Good point. Once the playback EQ has been set, it doesn't need
adjustment. In fact, most tape decks //don't// have adjustable playback
EQ! The curve is standardized.

So the OP doesn't really have a problem. Even if there //is// a pot in
the playback EQ, there should be no reason to touch it.



Dolby B dynamically adjusts the curve slightly. Are you trying to
calibrate with a compander running at the same time? When all else fails
use your ears, after listening to your favorite source material on the
same speakers. At 1+7/8 ips it's a miracle they work at all.
