K&K Phono Preamp questions.


On the front of this unit there is a polarity + mute and - knob. Is the polarity + and - in regards to the xlr outputs? Also on the back panel, there is a switch near the xlr pin 1 ground label. Is this a ground lift switch? Any and all help and other pointers regarding this unit are more than welcome. Thank you.

Well, I'll call foul on the member that said Kevin designed around the Russian tubes. That may have been the case decades ago.....I spent several hours listening with Kevin in my pre-Trio stage. His tubes of choice then were Reflektors. Actually, the original Reflektors were replaced with a different batch that sounded more linear. We both agreed.
I had just assumed the polarity switch on my Trio was regarding the music signal, not the AC polarity.
@lewm ,

I don’t think the OP gave us a mirror example of how his phono looks. The link showed a blank front plate with no company logo or the switching options he talked about.

That picture leads me to believe it may have been a customer built kit?
@wturkey,

My Trio uses 3 /6922 or variants. I would contact Kevin for accurate info. He actually has a blog on Audio Asylum which might be a better/quicker way to get in touch.
@wturkey,

Millercarbon is correct, it's all straightforward. Which do you own, the Maxxed-Out or the Trio? I own a Trio.
