I need some techy help in order a preamp--resistor values.

JB, the Khozmo is a very nice looking piece of kit. I can't help you with advice regarding resistors, my concern is whether your amp would have enough gain to use with a passive line stage. You didn't mention that subject in the specs you listed.

I don't know how much this piece will cost you, but just yesterday I received from Modwright an SWL 9.0 Linestage, and it just put me over the top in the chase for the sound quality I've been trying to attain for all these years. As my Virtual System is listed, I really am "Done For Now".

By the way the unit I got was a trade in, which has a new upgraded power supply, tube board, and new MWI capacitors, all for $1450, shipping and tax included. The much, much better preamp you are seeking may not cost as much as you might think.

Good luck with your search for a preamp, regards,
Dan 

@jbhiller,

I would recommend you to check out Aric Audio. He can custom build anything to your exact needs.

I have recently completed a project involving a custom 300B amp. Even though I only have about 100 hours on them, I can say without any hesitation they are the best tube or SS amps I ever owned. One would probably pay 3 times elsewhere to achieve this kind of performance and attention to detail. 

The Elekit TU 8600 amplifier already comes with a volume pot built-in, what you need is change it to a higher quality same value pot, use a line level sources selector as preamp.

Wow! Fast responses--thank you. 

I can't find any specs on the Elekit's gain.  I'll email them. 

The kit is built and been in use for nearly 2 years. There's no fear of soldering here.  I was just looking for a reasonable suggestion/starting place. 

The reason I want a preamp is that I have 2 line level sources (Elekit has one line level input) and I can't live without a remote any more!  There--I admitted it. :)  There's not enough room for me to add in a motorized attenuator and I can't seem to figure out how to fit another set of line level inputs in back.  

This unit sounds wonderful.  So long as I don't push it too hard, it bests my Primaluna Dialogue Premium.  I just wish it had two inputs and a remote!

Aric is a great thought.  I've been curious about his work in the past. 

Atmasphere your suggestion intrigues me too.  As always, much appreciated. 

Jb, just FYI, the Modwright has a built-in remote volume control that is smooth and quiet, and raises (or lowers!) the volume in small enough increments that won't aggravate you with too large a jump in volume.
