7 Band Equalizer.

Basic parameters: 1. Operating voltage: 3V-12V (voltage below 4V will significantly reduce the sound, the maximum can not exceed 15V); 2. Operating current: 1mA (static) to 150mA (max); 3. Output speaker impedance: 4Ω-32Ω (impedance high-sound, high efficiency, if not confident of their own speakers, you can buy shop selling speakers, the sound is very loud); 4. Support the speaker power: 0.5W-25W (In fact, any power speaker can be used, the volume and the speaker power is not much relationship, as long as greater than the amplifier output rating on the line, a large speaker sound may be larger); 5. Output power: 750mW (max); 6. Volume: 22 (L) mm * 13 (W) mm * 7.4 (H) mm; 7. used to do the microphone pre-amplification is very good, very low noise and AC ripple, the output sig.

This kit have everything what you need to make your own A class amplifier. The original Hiraga Amp transistor are replaced with 2SC1775 2SA872 and on output NJW0302G NJW0281G. Decoupling capacitors are from Elna (Cerafine or Silmic II series), so everything is designed to satisfy very rigorous standards.

Note: This is DIY Kits, Need welding its by yourself! Not included 12AX7 / 21AU7 Tube! Power Supply: DC 180-300V DC 12V Using double-sided immersion gold processes Taiwan produced copper foot precision metal film resistors! Siemens high-voltage filter capacitor! Ceramic Gold-plated tube socket to ensure contact reliability! The circuit has a noise inaudible! The tube preamp circuit, because of its second harmonic distortion appropriate, connected to the power amplifier board with more bile performance! Sound performance rounded.

HiFi Art-Elfidelity. Phono Pre-Amplifier. AUX function is tube buffer function to get thebetter warm sound, so you can setup T7 work for AUX or phono by input selector. Reason B: T7’s RIAA function part broken.

Optimized for stereo sound with simple connectivity, the blackYamaha R-S202 Stereo Receiver features four stereo RCA inputs, one stereo RCA output for recording to an external device like a CD recorder, and a 1/4" headphone output.

Note: this item is only Bare PCB Board, not contain other parts. PCB size: 130*70mm 1.6mm thick, spray tin process. Ground Grid gg tube preamp Power supply board, it can also be applied to other tube pre-amp board, high voltage output high voltage can be changed by changing the zener diode. The low voltage output board can be adjusted directly. Note that the high-voltage output current of this power board is recommended to be within 1A. Low pressure is less than 1.5A. Low pressure up to 2A. More than 1.5A. The LT1085/LM317 pay attention to enhanced heat dissipation. This PCB reserved two 5W Zener tube package positions, for the serial connection method, when the output voltage is 200V, 200W voltage regulator can be installed, and the other needs to be shorted.

This is the PCB of a very low distortion preamplifier(Gain=2) that can convert an unbalanced signal to a balanced signal. The circuit make uses of a famous balanced line receiver DRV134. The chip can offer a distortion as low as 0.0005% at 1KHz and 0.001% in the whole audio frequency band (below 18KHz) when driving 600ohm load! Maximum swing can be 18Vrms at 0.01% distortion! The gain is fixed at 6dB(2 times). Supply voltage: /- 10V to / - 15V (suggest /- 12v).

Note: just empty Preamplifier board. free with Signal Switch board and cables. BP26 flagship balance preamplifier, the signal input is 3 sets of RCA 1 group BAL, the output is a set of RCA and a group of BAL. Board size: 267*145mm The output delay circuit is added during the design, and the output signal does not pass through the delay relay contacts to minimize the sound and dye. The front panel does not have voltage regulation and requires external /-24V (pre-stage power supply) and AC8-10V (select circuit power supply) access.
