DaVa FC-A1 a field coil contender
- Thread starter christensenleif@msn.com
- Start date
finally some shitty weather so I could reroute my DaVa fc supply wire on the Groovemaster and reconfigure the gnd scheme to The Head and then on to LCR riaa
now totally humfree
also got around to rebuild riaa yesterday to add a third input
2 MM and 1 MC with S&B SUT in fixed position for EMT mono and stereo in Alfred Bokrand 309 banana

Hi Leif. What cable did you use for the DaVa dc power cable duty? Was it shielded or not and what AWG?
All of Leif's cables were unshielded silver with cotton
If ever there was a place for shielding it would be this specific application.
Hi Leif,
By isolated do you mean physically separated only? I can see them on top of the arm. Before you had them going around the arm like a spiral in the photo.
I have been looking for small AWG shielded or screened cables for when I get the DaVa due to that proximity with signal cables.
coated and physically separated
yes I´d like som too....
first I had severe "motorboating"
then I revolved around armtube and reduced it
then yesterday I rerouted twisted and on top of tube and rearanged gnd.....
result no hum, but still slight motorboating on full throttle
guess a shielded one would solve that too
would need to take 13vdc 100mA or so

Okay will keep you posted in case I find something. I might try to find some Kondo IO Ltd owners to find out their solution.
tried to lift dc cable straight up from cart and there´s no difference in noise, so present solution seems pretty immune to pick up noise from dc cable, even unshielded
which means I´ll keep it as is.....

Got my cartridge yesterday, took like half an hour to put it in place. And WHAMMM, it took me really by surprise: this is high resolution vinyl with everything in spades but wonderfully well balanced! It gives an additional insight into large instrumentation as small baroque ensembles or voices. Previous cartridge was a Lyra Etna.
Still has to burn in of course so it will only get better over time.
For the moment 3.3 grams of downforce but can be reduced to 2.5 after about 30 hours of playing.
Mounted on the FCL tonearm from Primary Control.
As from the first moment, no humming or anything. Again, plug and play for me this was.

Great news!
You have this baby on it's way to you too, Bill?
I have to say if anything was gonna make me move on from my Straingauge, this would be the one.
I know it's in the €3-4k region. Are audiophile quality FC psus particularly pricey?

Since our reference speaker uses a field coil driver, and knowing what that does, it would be so cool to hear it at the other end! I will have to consider this for the next iteration here.

Glad you liked it too
Always risky with persistant recommendations
Enjoy
Yes ordered and deposit paid. I take my delivery in September.
Sorry forgot to respond to the power supply question. It comes with a FC power supply for a very small fee (couple hundred euros) and all the feedback thus far is based on this.
In answer to your question though - like anything in audio you can spend as much as you like on such things. I for sure will be trying out valve based power supplies for it without a doubt and possibly other more fancy ss ones if that proves too challenging.
Thomas Mayer makes a speaker field coil supply that I am sure can be tweaked for this application (would need to see voltage and amp specs) but since it is a bespoke item, I would think he can make it. It is 5250 euros. I believe it is solid state.
