HA-1A integrated/headphone vacuum tube amplifier

• CHARACTER
  • Two EL84EHs are used for class A S.E. amplification.
  • The toroid power transformer and EI audio transformer are specially manufactured for CAYIN HA-1A by applying our unique workmanship, which has low magnetic leakage, wide frequency response and low impedance.
  • One 12AX7 and one 12AU7 are used in the preamplifier.
  • Can use as one high quality preamplifier (14dB).
  • All-vacuum tube design, all hand-made.
