FEATURES
· Use two EL34, two 6SN7 and one 5AR4 tubes.
· The first two stages use triodes of 6SN7 which are configured as common-cathode and cathode follower.
· The output stage uses one EL34 tube configured as class A amplifier with single-end output.
· Output power can reach 10W for each channel.
· Built-in rectifier and LC noise filtering circuitry.
· Symmetrical layout design in signal paths for both channels.
· Dedicated ground and power rails layout design.
· Two large reservoir decoupling capacitors for power rails.
· Power requirements: two 260V AC (100mA), one 5V (2A) and two 6.3V AC (1.5A)
· PCB dimension: 218mm (W) x 132mm (L)
· PCB thickness: 2.4mm, double layer, 2oz copper.
