Description

Product Details：

This amplifier board adopts a single differential circuit with extremely low crossover distortion K170 field-effect transistor is used as a differential tube, and there is no reverse voltage at the gate. The coupling capacitor can be removed to further reduce coupling distortion Due to the lower low-frequency diving of single differential circuits compared to double differential circuits, a four transistor composite amplifier is used in the voltage amplification stage to compensate for the low-frequency diving problem Excellent circuit design, combined with field-effect transistors This makes the circuit perform exceptionally well in all frequency bands The power has also reached 80W * 2, which can meet the needs of most HIFI amplifiers.

Type A: Using HITACHI transistors (2SK1058/2SJ162)
Type B: Using VIVSA transistors (IRF9240/IRF240)

This amplifier board adopts a double-sided design
Taiwan produces metal film with 1% error and high-precision coarse copper pin resistors
The load resistor adopts Japanese made KOA non inductive power resistor
WIMA film capacitors from Germany
ELAN/Panasonic electrolytic capacitors from Japan.
Integrated horn protection circuit on the board.

List :

1 pair x Goldmund Circuit amplifier board

Attention:

Class A amplifiers operate in a constant current state and require the installation of a 4kg or more heat sink. The heat sink temperature is very high Do not touch to avoid burns.

After receiving the power amplifier board, do not adjust the potentiometer on the board casually to avoid excessive static current burning out the components.

If you have any questions, please feel free to contact us at any time To avoid unnecessary losses.
