Description:
Name: IRF250 large tube version, 1 channel per board
Power supply: DC 18-50V (Recommended switching power supply); The current can be adjusted from 10mA to 60mA. The lower current will make the sound better, but if the current is large, you need to make the heat sink larger.
Output Power: 1W-30W
The flow speed is 0.03 - 0.06 A (10 - 60 mA).
Features:
It has low distortion, strong and transparent sound characteristics.
After a long listening time, the bass is strong, flexible and not fatigued.
Another benefit is to generate low heat and save on radiators.
The current is adjustable from 10-50mA (0.01-0.05A) and the sound of 30mA (0.03A) is very good.
Set the universal meter to 10A or 20A DC gear, connect two test wires to positive power supply and sequence, adjust the 502/103 (5K / 10K) adjustable resistance to change the power supply.
The flow speed is 0.03 - 0.06 A (10 - 60 mA).
Package included: a pair of power amplifiers
Note:
Before power-on, check the power tube to insulate and then install the radiator.
