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


Thank you in advance!
I'm thinking of ordering a Khozmo preamplifier until I can afford something much better.  I'll be mating it with an Elekit TU 8600 amplifier. 

The Khozmo website gives options on resistors.  See https://khozmo.com/stereo_selector.html#remote

The Elekit has the following specs:
  • Tubes: 300B x 2, 12AX7x1, 12AU7x2 
  • Rated output: 9.2W + 9.2W (10% THD)
  • Rated input: 320mV
  • Residual noise: 36uV (IHF-A)
  • Frequency response: 7Hz-40kHz (-3dB)
  • Input impedance: 50kΩ
  • Output impedance: 4-6.3Ω, 8-16Ω selectable
Any intel and advice will be appreciated!

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 
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.
