Pearl Two

[6L6]

I currently am using a Denon DL-110, a high output moving coil. 1.3mv output.

Hopefully, after a bit of horse trading, soon I will have a Shelter 501. 0.4mv

[Tea-Bag]

I use a sound smith Modded DL-103 with a ruby cantilever. With this sound stage, and some step-ups I am blown away. I finally realize the potential of a vinyl rig.

Are the Pearl 2 boards and/or part kits still available?

Thats on the Pass diy.com store on his site. Yes they are still available, and come with the matched fets.

Finally done. I put this off last year and this winter got motivated again
Didn't have any serious issues surface
I used solid silver in teflon tube and shielded it a gutted RG cable for the internal connection of PCB
Power wiring is a 3 wire braid with copper shielding. Gain pcb is isolated, its enclosure is shielded thru power shield and terminates inside PS case
Signal path I used PRP resistors and 1837 caps with Silmac 22uf output
Been running it in for about 5 hours with no heating of any components just 2C more on + reg than - (28C)
have tried 2 low output MCs so far from my collection Accuphase AC2 at .17mv and a Fidelity research mk3 at .14mv
My final system uses a Winlabs Jewel at .4mv output
No hum issues yet
Used a plastic milk carton plastic to shield the mur860 and housekeeping pcb at the AC entrance
will post pics when I figure out how to do it from my powerbook (always have difficulty)

regards

Congratulations!!!!! Nice, Isn't it?? I am in love with mine.

We are looking forward to seeing the pictures!

Which value resistor did you use for R14? I assume you went to 300 ohms for a full 65db of gain with those LOMCs.

[AVWERK]

I used 300. I might change this when when I put it in my main system (Audible illusions 3a) line section.
Have been testing with an Audio Alchemy DLC I pulled out of closet.
BTW Don,t change removable headshells/carts without turning the unit off first or you will take a quick trip to the bathroom to clean up! Talk about motor boating....

Do you find that there's enough gain using 300 ohms?

I know what you mean. Pulling a turntable interconnect out of the Pearl with the amp turned on will also result in house-shaking jolt and a trip to the bathroom

Remember, this is just a burning phase and haven,t put it in my regular system yet. Right now it goes into a DLC to a B&K amp to Monsoon desk top speakers. My regular system is an Audible illusions 3a- Sota Star ET2 air arm/ Krell 100 monos/Quad ESLs or Martin logan SL3's, Vandersteen 2wq

If something going to go thermal, I'd rather have the Monsoon go nuclear than the others if you know what I mean..
Why can,t I drag pics from my desktop to post area... Always a problem for me
