Since 2 years preparation and testing , Laochen in the end release their latest flagship big power 845 tube amplifier
Use one high voltage transformer and one lower voltage transformer, 2 x power transformers independently supply amp, in order to ensure amplifier's power at the same time reduce the interference, in the absence of output feedback, the noise is controled within 1-1.5 millivolt, making the sound of the amplifier more broadly natural.
Using custom 6SN7 preamplifier,
PSVANE 300B-SE to drive PSVANE 845 high-power bile duct drive output transformer,
Between 300B and 845 is with stable efficient hi-fi coupling capacitors
Use of metal film resistors, ALPS potentiometer and hi-fi level capacitors,
signal amplification part use handmade scaffolding design to reduce the noise
The power supply part use thickened circuit board.
use for each high voltage and low voltage two inductance for filtering,
Use a delay of 30 seconds of the circuit, effectively protecting the life of the power tube.
Taiwan's high-quality dual-head dynamic VU meter,
Direct thermal triode 845 amp, both the performance of human voice and natural string and delicate, and also when dynamic time it's calm and magnificent,
3 groups of inputs.
