A number of YuSynth modules benefit from having matched Hfe transistor pairs including the Steiner VCF, Wavefolder and the VCA.
You can match your own transistors if you have a multimeter with a transistor gain range or alternatively you can purchase them from us at Soundtronics. The BC547C has a Hfe range of 420 to 800 so we use an Atlas Component Analyser to match the gain of each pair to within a hfe of 7 which is better than 1%.
