Use a square power transformer specially developed for this machine. The output transformer uses two high quality wideband EI output transformers. The voltage amplification and boost stage uses a 6SN7 for power supply filtering. The voltage amplification stage and the push stage use two pairs of 6SL7 and 6SN7 tubes, respectively. The rear stage uses four KT88/6550/EL34 tubes for class AB single-ended power amplification. Triode and ultra-linear selection are available. External independent BIAS-ADJ current display header. External EL34/KT88 tube selection function, easy to replace different types of tubes, adding endless fun. Infrared full-featured remote control. Use thick silver plated signal leads. With pure post-level function, it can be connected to independent preamplifier signal input. Power on mute delay function (about 30 seconds). Select Japanese ALPS high-end motor potentiometer. Easy-to-install plug-in tube shield.
