Features & Compatibility

Product parameters:
2022 balanced version: with single-ended, balanced 2road input can be connected to 2 pre amplifiers, using relay switching
Output power: 60w*2 (8 ohms), 120w*2 (4 ohms), 240w*2 (2 ohms)
Output large tube: each channel uses 5 pairs of Sanken tube king C2922/A1216 in parallel, the thrust and low frequency are very good
Class A current: 300mA per pair of tubes
Main transformer: 1 Nippon Steel core 800w transformer or 2 British Talema500w transformers
Radiator temperature: 50 degrees, don’t put it into the cabinet, 15 degrees in the cold machine to 50 degrees in the hot machine, about 20 minutes, listen to it after the warm machine, different sound quality

 
 
 Description of 2 kinds of transformers used by A9

The difference between the two models of A9
Model	Transformer capacity	Support power supply voltage	Transformer voltage	Quiescent Current	Output Power
A9 Nippon Steel version	800w Nippon Steel Transformer x1	AC110V, AC220V optional	AC30*4	Each tube 300mA	60w*2 / 8ohm
A9 T Transformer Edition	500w UK Talema Transformer X2	AC220V	AC30V22	Each tube 300mA	60w*2 / 8ohm

 A9 class A amplifier:
With 480 (width)*430*170 (radiator height) super large size, 15mm thick aluminum panel, 5mm thick upper and lower cover aluminum plates, the heat dissipation performance of the whole machine is super-class, and the weight reaches 28-32kg

 2022 balanced version has single-ended, balanced 2-way input, can be connected to 2 pre-amplifiers, using relay switching

 The following figure shows the power soft start and power filter part:

 Each channel has 5 pairs of Sanken tube king C2922/A1216 in parallel, 6 pieces of 10000uF large electrolysis:

 The following picture shows the TALEMA version: using 2 500w fully poured (effective anti-vibration) British talema transformers

 A giant radiator is used, and the temperature of the radiator is around 50 degrees:
