Cool breeze FU29 parallel single-ended class A tube power amplifier Teana A300 tube power amplifier Bluetooth 5.0 Bluetooth requires a pairing password, the password is 0123

Now there is an upgraded version of FM30 to replace FU29, the power reaches 12W, the sound will be gentle, if you need this version, please contact me for a free upgrade!

The Russian product name of FU29 is FY29 and the American product name is 829B. It is a composite tube in which two Cambodian tetrodes are packaged in the same glass shell. It is used in a parallel single-ended Class A output power amplifier. Units with the same parameters in the tube are used in parallel. FU29 filament voltage is 6.3V, current is 2.25A, screen voltage is 600V, curtain grid voltage is 200V, zero letter screen current is 40mA, full letter current is 110mA. The grid bias voltage is -18V, the optimal load impedance of the screen electrode to the screen grid is 13750Ω, and the output power (effective value) reaches 10W when connected in parallel and single-ended. The circuit of this unit is simple. The preamplifier uses a composite tube 6N2. In this way, a single channel can use 6N2 and a FU29 to complete the power amplifier task, and it has 10W single-ended pure nail power output. This machine is small in size, unique in shape, but strong in thrust. Do not use the power of ordinary transistors or digital power amplifiers to analogize the actual thrust of this tube power amplifier, because of the high power supply voltage and unique output cow structure, the output internal resistance change is relatively small for high and low frequency signals, and it has good low frequency driving ability. And the sound is soft and smooth, warm and delicate. This is why the tube amplifier has not been completely replaced after the emergence of many new technologies. Dimensions: 194 width X159 height X311 Output power: 10WX2 (pure A, equivalent to 50W thrust of A and B) Packing list: FU29 power amplifier X1 (No other accessories) Weight: Packed according to 10KG
