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.

Thanks for the feedback. I'm not sure which exact unit this is. It's got the 2 cork knobs on the front. It's very similar to this unit.

Thanks again for the help.
I can tell you that you have one very fine phono stage. I have owned mine for 20 years and is now the maxxed out version. I have no desire to change to anything else.

Looks like the one you have is a pretty old version. Don't know how it compares with the new full PCB-based ones.
Gotcha. Thank you for the feedback. This K&K is a difference maker. As soon as the unit was fired up, it was a wow moment. Any tube recommendations from current or past owners? No idea what tubes are in this unit. They sound quite good, to these ears anyway.
@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.
