3 chassis? Awesome! I have to know how you grounded it...

Also, are those R-cores? Where did you get them?

Nice analog rig by the way. I would be curious to hear your opinion of the Pearl 2 once you put it to the real test.

What I like about mine: very quiet, lots of gain, huge sound stage, solid bottom, extended top, high resolution, yet non fatiguing. What I am still unsure about: dynamics, and vocals - the latter seem recessed a bit, but this could also be the cartridge (VdH MC One) or its alignment. Overall, I love it.

The pcb is floating from its enclosure along with the rca,s
The bnc style connector,s outer barrel connects to pcb,s case
I braided the 3 wire power cable (kimber style) floating +\-/sigGD to pcb

Now I put copper braid shielding over the power cable connecting bnc so pcb case is grd.
It terminates inside the PS floating for now (still a work in progress)

The brass ground connection is isolated from its case. This is the signal star ground that connects the pcb,PS ground points, caps etc and the 35amp rectifier mentioned in waynes article
The AC power cord is foil sheilded, but I have not connected it yet. It enters the case on the bottom right into a copper pipe and terminates At the back top to the small pcb that has the fuse,cl60, 4.7 ohm 2 watters, ac cap (xono) style.
The earth wire connects to the PS case. I have not tried a 10ohm/cl60 combo yet here. I haven,t explored the full potential as I need to terminate the power cable shield and foil ac wire to see if any residual noise can get lower. It,s faily quiet now, but I have to put into my regular system. I,m not done yet

David

Oh, the rcores
They were labeled 2x24 at 115v and were actually 2x28 that put me at 40.5 vdc unloaded. I was going to rewire them and still might. I have run right at the limit of the regs at 40, but have backed it down with a small variac for now to 34 vdc.
Still a work in progress
Cant remember who I got these from last winter, but it was an ebay seller and his email sig was john 630 or something. Very expensive when you factor shipping to USA.

David

Just listening to what I got so far, it hasn,t grossed me out yet nor produced any fatigue yet. The idea of passing a signal through a 22uf cap didn,t turn me on the whole way, but so far I have to admit those silmac caps seem fairly transparent. Burning it in with fast piano records and of course
Al Demeolia's Elegant gypsy album...if this album doesn,t get your needle cherry red, nothing will!

We,ll see what we get once the dust settles.
Regards
David
