FiiO EA13 28W Class-A Stereo Vacuum Tube Power Amplifier

The FiiO EA13 is a pure Class-A push-pull stereo vacuum tube amplifier featuring two SYLVANIA NOS PCF80 preamplifier tubes and four JJ ELECTRONIC EL34 power tubes. It delivers up to 28W per channel through dedicated 4Ω and 8Ω speaker connections.

Custom EI silicon-steel output transformers, selected metal-film coupling capacitors, and large-capacity Japanese NCC filter capacitors support wide bandwidth, low noise, and the smooth tonal character associated with traditional tube amplification.

Four RCA inputs, a front-panel headphone output, mechanical VU meters, a 40-step analog volume control, and 12V trigger connectivity make the EA13 suitable for a wide range of two-channel audio systems.
