standard AB bias heatsinking versus enriched class A
I wonder if anyone has done the thermal calculations for what is the maximum
enriched class A bias for AB ? compared to standard optimum biased AB. i.e.
how much class A can you run within normal AB biased 1/3 continuous power
heatsinking ? i.e. that no extra heatsinking is required, static heatsink
temperature is the same as the the 1/3 continuous power soak test.
And what would the two output stage heat dissipation profiles look like ?
I cannot work out if extra heatsinking is always needed or not .....

I have not done the calculation but there should be plenty of info to allow it to be predicted.
