Rare TRIODE TRV-A300SER Fully Working with Optional Wood Panels
Product Details
TRV-A300SER
Triode Vacuum Tube Integrated Amplifier
With optional side wood panels attached, it produces a rich, lustrous sound.
Product Overview
The Triode TRV-A300SER is the successor to the TRV-A300SE. Upgrades include a more luxurious chassis (changed from a vertical to the common Triode horizontal design), separated transformer cases (independent covers for the power and output transformers), a wireless remote control (for volume adjustment only), and an MM phono equalizer (transistor-based).
Furthermore, the rectifier circuit, which was semiconductor-based (diode) in the TRV-A300SE, has been changed to a vacuum tube system (5AR4), further improving the richness of the mid-low frequencies and the smoothness of the mid-high frequencies.
The non-feedback/feedback mode can be switched using a small switch located on the front right of the top panel.
The vacuum tubes used are ECC83 (12AX7) for the first stage, ECC82 (12AU7) for the driver stage, and 300B for the output tubes.
Inputs include one PHONO/1 and three LINE inputs, with one TAPE-OUT provided. The input sensitivity is 800mV, which is relatively low for a vacuum tube amplifier, making volume adjustment easy at low listening levels.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
