    Completed VTA ST120 2018

    Post by Kramer on Mon May 14, 2018 12:27 pm

    Ordered the st120 Kit earlier in the year, has been completed for a few months now and I find myself listening more and more. I got the auto bias board installed recently, highly reccomended to everyone. Figured I would share some photos of the completed, for now, amp.

    It is powering a pair of 1982 Klipschorn loud speakers I was lucky to find a good deal on. I took some time rewiring the drivers and had some new crossovers built.

    Here is the amp with flat black transformers, I used some 3m thermal tape and heatsinks I had around on the back of the power transformer to keep it cooler in the summer.









    The new crossovers that I had built. Deans superX


    Klipschorns with original Crossovers



    Let me know what you guys think, still want to build some larger wood horns to replace the k-400's.

    Adding the bias-board with fuses and solid state rectifier really cleaned up a bunch of distortion. Made a new set of interconnects using Neotech LEST as signal wire, KLEI absolute harmony plugs, and silver plated copper neutral. They sound very nice.

    These cables are all very nice and cheap to build. Greatly improved my listening experience. If your going DIY I highly suggest giving them a shot.
