At the rear is one toroid tranny and in the front are two torodial 6mh chokes, one for each rail.

Mark, can you explane this to me please?

By the way Aaron :
I am right in reading that you built the Vifa Basis into an active speaker with class A amplifiers, supposing 4-way also means 4 amplifiers per channel ?

hi Jacco
actually thinks have changed;

Second monoblock is almost finished (today?). Last problems gone (earthloop)
Like it?😀

Yep. like it a lot.
With that thread you even brought me to doing the same.
I already built two Aleph 4's , and going to add 6 Aleph 5's.
I posted on the Pass Monster thread a couple of weeks ago.
On the shelf are still 48 Mallory 78000uF caps, and 24 Amplimo 300VA toroids. (both acquired the economy way).
The BMM crossovers i am not going for, though built quite nice.
I still have loads of opamps: 5534,5532,2134,627,637 etc.etc.
Thought of doing the active crossover the Danish bloke developed as i still had 50+ LT1028's, but i dont.
Hoping for an active single ended crossover by the time i have finished the Aleph's, dreaming does not cost.
When you posted your active amp thread i did not have a clue on the chassis numbers you mentioned before the amp references.
Hence my question, you have me puzzled on the speaker design.
jacco.

and for the design;
the two SS8555's will be placed in a 100ltr closed box. Sand-filled walls and seperate compartments. Lead and vilt and Pritex on the inside.
Seperate satellite with mid&high, very small(3.5ltr) and heavy.

Mark, can you explane this to me please?"
Yes, Its like a dead short winding around the toroid if you do this. The toroid won't like it much. One reason there's an insulator above and below all open mounted toroids.

yes I noticed that! 0,5V and 15 amps and the bolt got very
.
Modified all 8 toroids and the mechanical hum is completely gone.
Sound has improved also🙂
