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 13750O, 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.
This machine is suitable for pushing general bookshelf speakers and some floor speakers with high sensitivity. This machine adds a new Bluetooth 5.0 receiving module to facilitate the wireless connection of portable devices such as mobile phones. 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.
