Hello all,
I am familiar with adjustments for the hafler dh 500 and gfa-5500 amps but have not done a gfa-5400 yet. I just purchased one and one heat sink is much cooler than the other and I wanted to go through the bias and dc offset . I want to know which pot is for bias..Im guessing then lower pot but what are the settings and where are the measurements taken..thanks very much to anyone who can help..Roger
