PR-800 amplifier board

PR-800 amplifier using high power output design, the tubes are used in high-voltage and rigorously tested selected, the input works ON the 2N5551 2N5401, voltage amplifier stage with two pairs of audio signals tube is ON MPSA42 MPSA92 in parallel amplification, to increase this level of current output capacity and linear.
Specifications:
Model:PR-800 Amplifier Type: HIFI Output Power:1000W/4Ω X2 Impedance:8Ω/4Ω/6Ω/2Ω Size:12*8*8inch/31*21*21cm Weight:7LB/3.2kg
Technical Parameters:
Supply voltage: DC ± 20V to ± 95V ± 40 recommendations to use within 80V auxiliary power AC6V-15V A Class Maximum Power: 100W (RMS) ± 45V power supply, load 8Ω, total quiescent current 2.5A Harmonic Distortion: <0.01 10W / 8Ω Frequency Response: 0Hz-160KHz (-3dB) Conversion Rate: 25V / uS SNR:> 95dB Gain: 40 times
Precautions:
1.The board uses the capacitor voltage only 80V, the DC power supply voltage can not exceed

± 80V (for AC voltage is 57V), such as the need to use higher voltages, the need for higher voltage capacitors. 2.Board no rectifier bridge, the need for external rectifier bridge. 3.The board is a dual mono setting, 2-channel power needs completely independent

is not recommended for 2-channel common source or common ground. For 2-channel power sharing

likely to cause instability and even hum. 4.Amplifier board such as working in a high-voltage power output state, heat is very large

we need to add another original radiator fan assisted cooling, otherwise it will overheat burn! 5.Amplifier board has a variable resistor for adjusting the quiescent current, if necessary

can be adjusted according to your request quiescent current.
