Dear TAD enthusiasts,
sorry in advance for the long and highly specialized post. I am in the process of building the TAD 2402 clones and I am putting together info on the xover. A couple of points that are confusing to me when looking at the french melaudia site, the hand drawn schematic by jeanphilippe and the posts by Marco Gea. I want to make sure I get the details right and I would appreciate any help.
I am afraid to post schematics here but these are readily available on the aforementioned site under the 'Filtres TAD/Kinoshita pour TSM et TSM like' thread. Of course I could post my questions there as well but I am trying to keep all my eggs in the diyaudio basket. 🙂
1) Marco Gea revises the schematic saying that L1 = 2.7mH but the hand drawn by jeanphilippe says L1 = 3.4mH.
What do you guys think?
2)I have seen people mention different kinds of HF attenuators. There are even two different schematics, one printed and the other by jeanphilippe one showing a 2 pin connection the hand drawn showing a 3 pin connection. I see mention of constant impedance attenuators and I was recommended the fostex attenuator. That's a transformer based one with primary and secondary so 4 pins. That seems different from the printed schematic that has only 1input and 1output. The transformer R100T2 based should be connected as shown here:

Does it mean that the following RLC section should be connected on the secondary downstream of the attenuator?
To keep it all in the Matsumoto family, I bought a pair of Pioneer AT 8S attenuators hopefully they are fine for the application.
Kind Regards,
