Package : Yes Bundle : Bundle 1 Dimensions (WxHxD)) : 224*170MM Model Number : 6V6 Compatible Audio amp; Video Equipment Style : Amplifier Brand Name : SENGTERBELLE Certification : NONE Origin : Mainland China Product Details: Based on the British AN EL84 tube amplifier circuit. Voltage amplification and phase inversion are performed by ECF80 (6F1) electronic tube. The power supply is ordinary bridge rectifier and CRC filter. The characteristics of EL84 and 6V6 are similar, the power supply voltage and the driving voltage are also relatively close, and even the output transformer can be used universally, so we keep the driving and inverter circuits unchanged, and the current amplifier circuit of 6V6 is calculated according to the characteristics of 6V6. The traces on the circuit board are all tin-sprayed, with a copper thickness of 2 amps and a board thickness of 2.0 mm, using FR4 grade materials. The filament of this board is powered by AC, but the signal-to-noise ratio is quite high, and there is basically no noise. The sound of this circuit is a little different from the sound of EL84. Generally speaking, the sound of EL84 is a little more modern, refreshing, and has a slightly better line. The sound of 6V6 tends to be thick, especially the mid-bass is full and pleasing.
