X30 Flagship Electronic Tube Amplifier Single-ended HiFi Class A Power Amplifier with 2x300B and 2x845 Vacuum Tubes 110V/220V

Features:
- Made purely by hand, the whole machine adopts shed welding.
- Two EI type single ended output transformers made with Z11 iron core, featuring special craftsmanship and high-quality wideband response.
- Use a high-power power transformer fused with a Z11 iron core and special materials.
- Two ECC81/12AT7 and two 310A vacuum tubes are used in the front stage; The driving part adopts two 300B electronic tubes and a driving transformer coupled to the rear stage, with a full and round sound and abundant dynamics.
- Two 845 vacuum tubes are used in the rear stage for Class A single ended power amplification.
- Five sets of signal inputs (BALANCE, CD, LINE, PHONO, PRE IN); this machine has specially added balanced input function and pure back-end function.
- Adopting for NIPPON HiFi grade audio specific electrolytic capacitors, for NICHICON electrolytic capacitors, and original M-CAP capacitors for MUNDORF, and for MULTICAP series audio specific capacitors. For Teflon wrinkled copper gold-plated vacuum tube socket, permalloy balanced transformer.
