In a world now flooded with tiny, cost-cutting transformers where iron, copper and therefore quality are all compromised, SB-LAB proudly goes against the tide. Our Mod. 4K5PP88 is the very opposite of mass industrial production: a huge audio transformer designed for push-pull applications with KT88 tubes in ultralinear configuration, featuring a primary impedance of 4500 ohm and a nominal power of 100 watts.
The photos speak for themselves: the visual comparison with KT88 tubes highlights the generous size of the core, the result of uncompromising design. No early saturation, no collapsing mids, no hollow lows. Just plenty of iron, controlled induction, low current density, full low-end response and no distortion even at high dynamic levels.
SB-LAB products are not made to be cheap. They are made to sound great, last over time, and bring out the full potential of your tubes. If for you audio is about substance and not marketing, then you are in the right place.
