Bellari pa555
TUBE PRE-AMP ZERO FEEDBACK PURE ANALOG

The bellari pa555 is pure simple fun. Imagine being able to add a single tube and volume control between your source and your amp. The result is clear unadulterated natural tube sound. The PA555 is a unique product that offers exceptional performance in a tiny little package that’s a tube rollers pleasure dome.

The PA555 uses a single 12AX7 tube running at 150 volts. The input signal is connected directly to the grid of the tube and all of the gain of the PA555 is from one 12AX7 tube. The circuit produces a whopping gain of 11.1dB. The PA555 has no feedback or integrated circuits in the audio path. It’s a pure analog gem.
