Telefunken EL34-TK Black Diamond Series Vacuum Tubes (Matched Set of Four)

This matched set of four Telefunken EL34-TK Black Diamond Series Vacuum Tubes is ideal for use in guitar amplifiers and hi-fi equipment in homes, studios, and live stage applications. For personal enjoyment or commercial recording, they grant a focused low-frequency response and smooth midrange frequencies. Supporting higher plate voltages than a 6L6 and higher grid voltages than a traditional EL34, these high-output pentode tubes deliver a characteristic "British" tone.

Designed to handle a slightly higher grid voltage than a traditional EL34

Great for guitar amplifiers and hi-fi equipment

Smaller in diameter and taller than a 6L6, and capable of a higher plate voltage

Commonly used in pairs in a Class-AB1 push-pull configuration

Each tube is meticulously measured for all critical parameters of performance including transconductance, gain, noise, and microphonics

Tubes are selected by hand, rigorously tested, subjected to an extended burn-in period for stability, and re-measured before final packing
