Description:
- The
board adopts 2.0mm double-panel design, high-precision copper foot
resistor, load resistance using Japan KOA non-inductive power
resistor, film capacitor using WIMA, ELAN
fever capacitor, the power tube uses a new original audio pair
tube (MJ15025 and MJ15024 tube) ，every channel with 3 pair= 6 tubes. The
excitation tube and the voltage amplification tube are respectively
used (MJE15035/15034 and MJE15033/15032) audio pair tube. The whole top
material of the board is neatly arranged, the circuit design is
reasonable, the sound quality is pure and with outstanding design . The sound is warm and smooth. Dynamic and powerful, general large-volume speakers can be promoted
Features:
- On-board integrated speaker protection circuit, the protection circuit
is provided separately and does not interfere with each other.
- Basic parameters of the power amplifier board:
- Power amplifier board input voltage: positive and negative 30V-60V DC input.
- Output power: Class A 50W+50W , Class A and Class B are 350W+350W undistorted power output.
- Output impedance: 4-8 ohms
- Speaker protection basic parameters
- Original Oulong silver contact relay for reliable contact
- 7812 regulated power supply, the performance is more stable.
- Power supply voltage: AC 12-18V 0.2A 3W
- The circuit starts while the red light of the circuit is lit for 3-5 seconds. ,The maximum load power is 500W, the midpoint potential drifts 1V, and the protection starts.
- Recommended transformer parameters: dual 28-38V dual AC output power (500W or more
