Solid state or Tubes preamp phono stage.
First, I would like to thank everyone for the positive comments regarding my Trumpet MC.  It's a design I am very proud of, being able to reduce the cost of a world-class differential tube phono circuit design down to a price regular folk can affo... 
Tube PHONO preamp interference - RFI, EMI, bad grounding?
Definitely WiFi or cell phone antenna too close to inputs. I've added a small RF filter to the front of my stages to combat this.    
Phono stage options - balanced with XLR both input and output...
I agree with lewm that cartridges are not inherently balanced (only 2 terminals), but a phonostage input can nevertheless create a balanced situation by providing the common mode reference (ground).  This can be done using a center-tapped primary ... 
Phono Stage to complement an Ayon Triton Integrated tube amplified

Cartridge Loading.....Part II
reset the loading to 47K, buttoned things up and called the wife in for a listening session.  Sure as heck both of us noticed the highs were crisper   This is a common trick for many listeners over 60.  Brings back the "airiness" of youth.  Do w...

Back to vinyl need phono stage help!
ZP3 will work great for you.  It's a virtually EXACT copy of my original CORNET design (long story there), but with an 0A3 added.  For half the price you can get a CORNET3 new, but it doesn't have the fancy chassis.

Phono stage hum - Rega Aria
Phono stage hum - Rega Aria
Something isn't getting a ground.  Use your fingers again.  If touching RCA shields lowers the hum, then you're on the right track.  Is there a power transformer near the tonearm?  What happens if you change MC loading to 47k, does it change to ju...
