1 pair PR800 high-speed Class A, Class B stage HIFI 1000W high-power field-effect transistor power amplifier board with heatsink

This power amplifier board uses new original components, and all components of the signal channel are preferred! All Taiwan copper resistance, all American ON/FCS triode, etc!

Note:There are 4 different versions of this power amplifier board:

option 1 . is to use the original FCS field-effect transistor to drive the crystal power transistor,1000 uf capacitance

option 2. The other is to use FCS high current field-effect power transistoroutput.1000 uf capacitance

option 3.   is to use the original FCS field-effect transistor to drive the crystal power transistorOriginal USA CDE 5600uf 80V capacitor

option 4. The other is to use FCS high current field-effect power transistor output  Original USA CDE 5600uf 80V capacitor
