May someone help me how to build a good working phase correlation meter? (schematics, tips etc etc)

Thank you very much

You don't build one, per se...you use a dual channel oscilloscope.

I think he may be talking about a meter that looks like a meter...you know...with the pointer thing that moves around. I'm not exactly sure how they work, but I think a Phase Correlation Meter has a line in the middle of the meter. When the needle moves to the right, the stereo program is more in-phase than out of phase. When it moves to left of center, it's more out than in.

Maybe the circuit generates a L+R and a L-R signal and then compares them. If they're equal, the needle is in the middle. If (L+R)>(L-R), the needle move to the right. The greater the difference between the signals, the farther the needle moves.

And vice versa for (L+R)<(L-R).

But I just made this all up. It may be completely wrong. And I don't know how to build one.

best,
Bob

this looks promising and uses a standard voltmeter, you would have to print your own scale though.

I do have a circuit drawing for a Neve (BA376 I think) phase meter, but don't have access to a scanner at the mo-
if you email me I could probably sort a copy out though.

A company called 'Canford Audio' sell a kit that comes complete with driver and calibrated 'Sifam' meter movement. Not too expensive either.

Actually, I just checked... Canford aren't cheap:

I stand corrected on this one...but I still strongly recommend using a dual channel oscilloscope for stereo phasing, of course.

and I liked Bob's ending on his post.

If you are generally unfamiliar with what an oscilloscope is and it's various functions, go here:

That should get you started with the instrument.
