TELEFUNKEN Elektroakustik is debuting three new models in its line of Black Diamond Vacuum Tubes at the upcoming 2015 NAMM Show in Anaheim (booths 6721 and 1878).
TELEFUNKEN vacuum tubes have been utilized in audio applications, both production and reproduction, for many decades, and this history continues with the introduction of these new production tubes, in partnership with JJ Tubes from the Carpathian Mountains of Cadca in Slovakia.
Each tube is measured for all critical parameters of performance, including transconductance, gain, noise, and microphonics. In addition, all are cryogenically treated to ensure durability, and subjected to an extended burn-in period to ensure superior stability.
The tubes are then re-measured subsequent to burn-in in order to guarantee that only the best, lowest noise tubes are offered for purchase
6V6-TK
The TELEFUNKEN 6V6-TK is newly manufactured and cryogenically treated rendition of the 6V6. Originally released in 1937 by RCA, the 6V6 is a beam-power tetrode vacuum tube for use in hi-fi audio equipment and music instrument amplifiers, utilized in popular guitar amplifiers such as the Fender Champ, Princeton Reverb, and Deluxe Reverb for decades. The Black Diamond Series 6V6-TK is a replacement for keeping the same performance and tone as the originals.
ECC82-TK
The TELEFUNKEN ECC82-TK is a newly manufactured and cryogenically treated rendition of the classic ECC82, commonly known by the American designation 12AU7. The ECC82 is a dual triode vacuum tube with medium gain and low noise characteristics, making it well-suited for hi-fi audio equipment and instrument amplification. It’s commonly used as a low-noise line amplifier, driver, and phase inverter in push-pull amplifier circuits, and can replace an ECC81/12AX7 for lower gain applications.
KT88-TK
The TELEFUNKEN KT88-TK is a newly manufactured and cryogenically treated version of the legendary KT88. The KT88-TK is a beam-power tetrode that shares similar applications as the 6L6 and EL34, and is one of the largest tubes in its class. Originally introduced by GEC in 1956, it became competition for the American-made 6550, but with the ability to handle a much higher plate voltage of up to 800 volts, the KT88 became a common choice for power amplification design.
