Luna tube phono preamplifier is top class product in Trafomatic Audio production .

The main advantage is that this preamplifier use very rare LCR method to apply the RIAA correction due to complexity and cost.

There are a total of only the finest components such as four C3g SE tubes connected in triode mode , two interstage and two line output transformers as well as LL1941 input MC step up .

This preamplifier also applies the separately executed power supply used low induction toroidal transformer as well as two high inductivity chokes and Mundorf MLytic HV electrolytic capacitors .

Luna features :

  • Built in step up transformers
  • Switches ground plane with input selection preventing ground loops
  • Balanced and unbalanced output
  • Separate low impedance CLC power supply

Luna uses two tube gain stages with zero feedback and passive LCR equalizer .

The input stage as well as output is low noise Siemens c3g German Post tubes used in triode connection. Every stage is loaded by transformers and this provide complete isolation of this sensitive circuit from the following components.

There are no capacitors in signal way except in RIAA correction where we used Silver mica ones.
