Description: Details：This circuit uses DYNACO's cleverly designed classic circuit.The 6SL7 (6N9P) serves as both a voltage amplifier and an automatic balancing inverter, with the 1K resistor being the finishing touch. This resistor is not only the cathode bias resistor of 6SL7, but also forms the tail of the inverter stage with the secondary of the output transformer, and is also the negative feedback resistor of the loop! Taking on three roles simultaneously not only saves parts, but also reduces the additional noise and distortion of parts.PCB size：175x160mmOutput power: 12W x 2Output impedance: 8, 4 ohmsFrequency response: 28HZ-20KHZBC and wima capacitanceTube model: 6P6P (6V6) * 4 = V2 V3 V5 V66N9P（6SL7） * 2 = V1 V4Work voltage：0-AC250V @300MA0-6.3V @4A3.15V-0-3.15V @3ANote：Diy Kit：all parts need buyer to solder it ，not included tubes ！Assembled Board：have solder it well ，not included tubes ！Power transformer ：https://www.ebay.com/itm/165671576034Output transformer：https://www.ebay.com/itm/165612973938
