VPI is bringing back the Magic Brick!

According to the new VPI newsletter, they are reintroducing the Magic Brick in black only.  It says it's while supplies last.

I have several of these and have always thought they worked quite well.

Does anyone know the price?  I couldn't find it anywhere.

I bought mine new for 50.00 over 20 years ago and I wish I had bought the other one that the dealer had at that time.  $150 a piece seems steep for a small wood box with iron filings in it.  Perhaps there is some fairy dust in them as well?

I wonder if brass shavings would work instead of iron? I have buckets of it laying around.

It isn't iron filings. It is slabs of steel stacked on one another and somehow connected.

Just wrap the transformer with low frequency high permeability mu metal and be done with it, oh, and leave the nut on the bolt holding down the transformer slightly loose so the vibration won't couple so strongly to the chassis and everything inside it.
