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!

The Khozmo is a great passive, to mate it properly you’ll need the source that ’s feeding it’s input to be at least 500ohms or less in output impedance.
Then order a Khozmo 10kohm series/shunt, this will then also be a great match into your 50kohm input impedance Elekit amp which is as you stated 0.32v input sensitivity

BTW Elekit made good stuff, I've got one of their preamps here, and was impressed with quality of the kit and the sound. Still nowhere near as dynamic or transparent as a properly mated passive.
