Tube Amplifier Amp Bluetooth 5.0 Amplifier 40Wx2 For Bookshelf & Floor-Type Speakers Assembled FU29

Description:
The tube amplifier encapsulates two Cambodian emitter quadrupoles into a composite tube in the same glass shell. Using it in a push-pull output power amplifier can reduce the trouble of matching tubes. FU29 filament voltage 6.3V, current 2.25A, screen voltage 600V, curtain grid voltage 200V, zero letter screen current 40mA, full letter current 110mA. The grid bias voltage is -18V, the load impedance from the screen electrode to the screen grid is 13750Ω, and the output power (effective value) reaches 44W at full signal.

In order to further simplify the circuit, the pre-amplifier and inverter are used as a composite tube 6N2, so that a single channel with a 6N2 and a FU29 can complete the power amplifier task, and has 40W power output. The machine is small in size and unique in shape, but has strong thrust. Do not use the power of general transistors or digital power amplifiers to compare the actual thrust of this tube power amplifier. Because of the high supply voltage and unique output cow structure, the output internal resistance change of high and low frequency signals is relatively small, and it has good low frequency driving ability. And the sound is soft and smooth, warm and delicate. This is also the reason why the tube power amplifier has not been completely replaced after the emergence of many new technologies.

This machine is suitable for pushing general bookshelves and most floor-type speakers. The power amplifier adds a new Bluetooth 5.0 receiving module to facilitate wireless connection to mobile devices such as mobile phones.
