6V6-TK Amplifier Tubes - BLACK DIAMOND SERIES
The TELEFUNKEN Elektroakustik 6V6-TK is newly manufactured and cryogenically treated rendition of the legendary 6V6. Originally released in 1937 by RCA, the 6V6 is a beam-power tetrode vacuum tube ideal for use in hi-fi audio equipment and music instrument amplifiers. The 6V6 has been used in popular guitar amplifiers such as the Fender Champ, Princeton Reverb, and Deluxe Reverb for decades, and the Black Diamond Series 6V6-TK is a perfect replacement for keeping the same performance and tone as the originals.

Preceded by the 6L6, the 6V6-TK is a lower-powered tube that gained much wider popularity and use. The Black Diamond Series 6V6-TK offers a robust tone and great overhead. The rigorous quality control and durable construction yields a dependable tube ready for the most demanding applications.

BLACK DIAMOND SERIES
TELEFUNKEN vacuum tubes have been the benchmark of excellence in all audio applications, both production and reproduction, for many decades. This rich history continues with the introduction of new production tubes from TELEFUNKEN Elektroakustik, in partnership with JJ Tubes from the Carpathian Mountains of Cadca in Slovakia.

Each tube is meticulously measured for all critical parameters of performance including transconductance, gain, noise, and microphonics. All TELEFUNKEN branded tubes are hand picked to be the best examples of Eastern European construction in the proud tradition with which the name TELEFUNKEN Elektroakustik has become synonymous.

In addition to the rigorous testing procedure, all new production TELEFUNKEN tubes are cryogenically treated to ensure durability, and subjected to an extended burn-in period to ensure superior stability. The tubes are re-measured subsequent to burn-in in order to guarantee that only the best, lowest noise tubes are offered for purchase.

FAQ

What is the difference between Black Diamond Series vacuum tubes and the JJ-branded tubes?
The TELEFUNKEN Black Diamond Series tubes are built in the JJ Electronic Factory in Eastern Europe based on their existing models. The Black Diamond Series tubes go through an extensive multi-tier testing and quality control process, as well as a cryogenic treatment in the USA to ensure they are the best representation of European made tubes. Each vacuum tube is burned in for 24 hours, tested for all critical parameters, cryogenically treated, and tested a final time. TELEFUNKEN Elektroakustik guarantees this by branding them with the legendary diamond logo.

What is the cryogenic treatment process?
After the initial 24-hour burn-in process, the Black Diamond Series tubes are placed into a cryogenic processor where a computerized system gradually cools them from ambient temperature to -300 °F (-184 °C), where it remains for 24 hours until slowly returning to room temperature.

What sonic differences will you notice with cryogenically treated vacuum tubes?
The cryogenic process is done for a number of benefits, both sonically and constructional. Cryogenically treated vacuum tubes have a lowered noise floor, less microphonics, expanded dynamic range with more tonal depth, and a more consistent tone for a longer lifespan. In guitar amps, Black Diamond Series vacuum tubes have more harmonic content and improved saturation, which results in a richer tonal quality and deeper overdrive character.

What effect does the cryogenic process have on improving the construction of Black Diamond Series tubes?
The cryogenic freeze process plays a key role in treating and strengthening the tube's internal metal construction. By bringing the tubes to these extremely low temperature conditions, the stresses of the internal metal structure from the high temperature manufacturing process are reduced and settled. This strengthens the construction as a whole. The cryogenic process also aligns the grain structure of the carbon in the metal to be more uniform, which yields a more efficient system with lower operating temperatures, longer life, and improved electron flow. The results are tubes with superior durability and stability. Preamp tubes offer expanded dynamics and a richer tone, while the power tubes are more stable and efficient.

What are the benefits of burning in vacuum tubes?
All Black Diamond Series vacuum tubes are burned in for a 24-hour period at real world voltages. One of the major benefits of burning in is to heat the cathode and remove any impurities or unevenness on the cathode coating. The cathode is the element in the tube that is heated and releases electrons. By burning the tube in, it reduces any popping, static sounds and erratic behavior. This is proven to benefit the vacuum tube's lifespan and durability.

What is the significance of the black ink on the new Black Diamond Series tubes?
TELEFUNKEN's Black Diamond Series tubes have been screen printed with black ink to clearly differentiate them from the original, white inked diamond-based TELEFUNKEN tubes, originally produced in Germany in the early and mid 20th century.

Can these Black Diamond Series tubes be used in TELEFUNKEN Elektroakustik microphones?
Black Diamond Series tubes have been developed for the Musical Instrument and Hi-Fi Audio markets and are excellent for use in applications like guitar amps, preamplifiers and power amplifiers. None of these tubes are currently used in TELEFUNKEN Elektroakustik microphone production.
