BUGERA premium-grade ECC83A tubes are hand-selected for their ultra-low noise operation and classic European tube tone – and are highly recommended for all guitar, bass and other audio tube amplifier applications.

Glorious Tone and Dependability

True to their classic roots, our high-end ECC83A dual-triode preamp tubes provide ultra-low audio and microphonic noise, and the sound that led to the famous “British Invasion”. With its beautifully deep bass, articulate mids and soulful highs, the ECC83A is ideal for blues, jazz, fusion and R&B – or any style where a rich and warm tone is desired. It also serves as an exceptional replacement for standard 12AX7s to tame an overly bright sounding amplifier. Our ECC83A is simply one of the best ECC83 tubes ever produced.

Quality is Always #1

Our state-of-the-art process begins with selecting only the finest tubes from all over the world. We then subject them to the most rigorous testing procedures, which are conducted in demanding “real-world” applications. Only about 10% pass the test and are given the BUGERA name and stamp of approval. The rest are recycled responsibly.

This highly labor-intensive process is an art we’ve mastered over many years. As a result, ours are the finest and most musical tubes you can buy – at any price!
