Elekit TU-8500 Tube Pre-Amp Kit

$550.00

In Stock

This is a preamp kit with a phono equalizer with the following features:

  • Precision phono stage RIAA equalization (CR not NF); supports both MM and MC cartridges.
  • Two low noise OP amps are used in the phono equalizer amp circuitry. OP amp preference are accommodated by use of socket mounts allowing easy substitution of alternative OP amps.
  • Two 12AU7 (ECC82) tubes are used in the line amp stage. Gain is switchable (Approx 1x to 3x).
  • Reduced hum/background noise circuitry includes a low flux leakage R-core transformer, a FET ripple filter for B-power and the tubes are powered by the DC power supply.
  • Sufficient space has been provided on the PCB for substitution of largest coupling capacitors.
  • Ideal complement to TU-8200 power amp.
