Note: this is a DIY kit. all the parts will need yourself to solder it.  the assembeld board photos just for reference only！！！

The default price are inlcude 2 channel amp kit.

   This amp board refers to the circuit design of  famous machine (PASS). This is a single-ended class A power amplifier circuit. It uses a high-grade double-sided thick gold-plated PCB (substrate 2MM, copper foil thickness 75U, not comparable to 35U), dual-channel mirroring design , Hifi component assembly (military industry 718 factory resistance  Ruby Hifi electrolysis, non-inductive high-power resistance, etc.), the power amplifier  transistors adopts the US brand new IRFP240/250 field effect  transistor precision pairing. The voice is mellow.

Note: Single-ended Class A amp Heat is horrible! (The quiescent current per channel is 1.8A!) Please do not power on the test without installing a radiator or installing a small radiator! So as not to burn the Power transistors! The recommended weight of the radiator is 5KG per channel. .
Size: 136MM*78.6MM, plate thickness 2.0MM.
Voltage: DC+－35V
Power: 60W (8 ohms)
Differential input field  transistor IRF9610 matching accuracy 0.2%, midpoint output voltage (+-50MV) within
The Power transistor matching 0.3% error.
