Description

New Factory Matched Quad of Telefunken Black Diamond EL34-TK Reissue Vacuum Tubes

The EL34-TK has been designed to handle a slightly higher grid voltage than the traditional EL34. Offering a tight low end and smooth mids, it will bring new life to guitar and hi-fi amplifiers while retaining the historic tone Telefunken tubes have always been know for.

Will work in place of: EL34, 6CA7

Testing and/or Matching

At VIVA TUBES, all of our customers get the same high standard of testing and matching. Some sellers charge more for premium matches but we believe all of our customers should get the same level of quality and service. 

Tubes are tested and/or matched at full operating voltage with regulated power supply on a Maxi Matcher tester for general mutual transconductance (Gm). In addition, power tubes are tested/matched by plate current (Ip) and preamp tubes are tested/matched by gain. Rectifier tubes will be tested for emissions on a calibrated military grade tube tester. 

Our goal is to match within 5% with an upper limit of 15% (15% is the industry limit to consider a set).

Hand written test data included.

Note that we do offer a few models which are tested & matched at the factory. They will be matched by the same parameters (Ip & Gm) but to the manufacturer's standards. Factory testing will be indicated in the item title and description. 

Guarantee

We offer a minimum 90 day guarantee covering functional defects - including noise unless otherwise stated. The guarantee period begins the day you receive your order.

    Telefunken EL34

    Posted by Tom on 9th Sep 2023

    I have replaced Genalex Gold Lion KT77 with these Telefunkens in my Mystere IA11 and I fully agree with Kevin review. The little warmth added did not diminished details and the bass became more defined. Very pleased indeed.

    Very nice surprise

    Posted by Kevin woodbury on 19th Feb 2023

    I been using different el-34 tubes in my mystere ia-21 integrated. A lot I like just different brands give you a little different flavor of sound. Usually when you have a new set of el34 tubes there is some warmth and compression in the tube until it burns in and settles in and becomes more transparent. These telefunken el34 tubes sounded great right from the get go. They are clear and open nice detail with the right amount of warmth in the midrange the bass is clean and tight. What a nice surprise this was. I know they are made in the JJ plant to telefunkens specs and then the cream of the crop is sent to Connecticut where they are then Cryo treated and tested and burned in again. These tubes are a very nice surprise indeed.
