Features of this machine:
1: Purely handmade, the whole machine adopts scaffold welding
2: Two EI-type single-ended output transformers with high-quality special craftsmanship and high-quality wide frequency response made of Z11 iron core
3: Use a Z11 iron core and a high-power power transformer fused with special materials.
4: Pre amplifier use two 6SL7 and 6WG7 vacuum tubes: two 300B vacuum tubes and a drive transformer are coupled to the power amplifier, and the sound is full and smooth , Dynamic.
5: Use two 845 vacuum tubes to enter Class A single power amplification.
Power-on mute delay function (about 30 seconds).
This machine is specially added with balanced input function and pure power amplifier function
9: Power-on high voltage delay and mute delay function (about 30 seconds)
11: Use ALPS motor potentiometer
12: Easy-to-install pluggable vacuum tube protective cover
13: Peripheral power tube bias current adjustment function.
