Some Ideas on Temperature Compensation for Audio Amplifier EF Triples

Temperature compensating an EF3 audio power amplifier output stage is not a trifling task.¬† There are 6 Vbe junctions, running at 3 different current densities, different temperatures and neither is the thermal performance of the heatsink assembly characterized in most DIY cases. This makes deploying a conventional 2 transistor¬† Vbe spreader (or Vbe multiplier as […]
