Tube Amplifier merk Oldchen 845 upgrade version. dengan tube yg lbh baik dan mahal bawaan pabrik.
second hand sekitar 1 tahunan. no minus, semua normal dan berfungsi baik. belum pernah servis.
Oldchen, a significant high cost performance brand in the tube amplifier industry, has established a positive partnership with PSVANE. This collaboration allows Oldchen to incorporate the latest optimal tubes from PSVANE into their amplifiers. In the case of this specific amplifier, all tubes are newly manufactured by PSVANE, offering exceptional value and sufficient quality to create a warm tube sound.

Input voltage for: AC50-60hz /110-120v, 220v 230v-240V
Features:
Since 2 years preparation and testing , Laochen in the end release their latest flagship big power 845 tube amplifier(HIFI EXQUIS)
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, (HIFI EXQUIS)
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 point to point and PCB mixed design to reduce the noise, and make more flexibility
The power supply part use thickened circuit board.(HIFI EXQUIS)
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,
Gold-plated connectors(HIFI EXQUIS)
3 inputs source with swither(HIFI EXQUIS)
Free offer tubes protection grille(HIFI EXQUIS)
All electronic component are high level quality
Manufactuer Laochen is most famous Chinese brand, they have 3 brands: "Oldchen" , "LaoChen", "Aiqin" , its EL34 series is already sold more 20000 copies.
