(US only).  YES - These work in the Klark Teknik KT-2A!  Many of the positive feedbacks I've gotten lately on Ebay are from people upgrading their KT-2A's.<br>There's a reason top manufacturers like Warm Audio, Stam Audio, Serpent Audio and Skibbe Electronics have Kenetek T4Bs inside - classic sound!<br>Kenetek has been manufacturing T4B's for over 20 years. During that time we have discovered how to make the *best* T4B's available - custom photocells manufactured to our specifications (not off-the-shelf parts), custom EL panel manufactured to our specifications, proprietary PC board incorporating a ground plane for lowest noise, and no less than 5 quality assurance tests throughout the build and test process. Each unit is assigned a serial number and test data is kept on every unit. Kenetek T4B's come with a 3 year warranty. If your T4B becomes defective simply return it to us for immediate repair or replacement.<br>Available in four different release times: Classic (Medium), Way Slow, Good Slow, and Good Fast. Please specify the release time you want. If none is specified a Classic (Medium) unit will be shipped. Classic Medium is the best overall choice for multi-purpose compression. Bass guitar and other low frequency instruments may be slightly better served with either a Good Slow or Way Slow unit. Guitars and fast, punchy vocals do slightly better with a Good Fast  unit. Drum overheads do best with a Good Fast unit.<br>Kenetek T4B's are in use daily by audio professionals all over the world for mastering, mixing and tracking hits in every genre. A new Kenetek T4B will restore that classic sound to your original LA-2A or LA-3A compressor.<br>Some comments by our customers:<br>"Just had to drop you a note to say how pleased I am with the two T4B's I purchased from you and received today, Friday - having just ordered them Wednesday. I had recently purchased a '70 LA3a as a companion to my '71 LA3a that I've had for 15 years. My old '71 has been working fine but my 'new' one had a failing opto with a super-slow release time. So I ordered a pair of your TB4's to hopefully keep the two units relatively performance matched. I compared the functioning 71's opto with your new ones and found the compression and release characteristics almost identical sonically. What a great product you have in these! "<br>-Gar Robertson<br>"Just wanted to drop you a quick line to tell you I've popped the T4 into my UA LA2a reissue, and it's transformed it miraculously (obviously, you knew it was going to do that, I didn't)"<br>-Lee Russell<br>"I did some experiments with T4B clones way back and it turned out that joe-electro´s version is closest to the original Urei T4Bs I have at hand. His stereomatching is perfect and he´s a cool guy to deal with. Many thumbs up!!! I can highly recommend his services."<br>-jensenmann<br>on GroupDIY.com<br>"KICK. ASS."<br>-Eric Boulanger<br>Bakery Mastering<br>"I have now used your T4B's for a month or so and I think they work exactly as they should. Compression is smooth and easily controllable. Perfect. Absolutely."<br>-Roni Martin<br>on GroupDIY.com<br>"Big thanks for getting these out. I don't know why anyone would buy elsewhere. Your T4B's put the magic back in my LA3A's while UA and others are getting out of line. Thanks for making a great product that keeps the vintage equipment enjoyable. Make Jim Lawrence proud!""<br>-Mappee<br>on GroupDIY.com<br>Note: Your T4B will have a different serial number and will come with its own Warranty Certificate showing the effective date for the 3 year warranty.<br>
