Do us all a favor, and ask Jac what his favorite dissipation level is on his EML 2A3s, where it lasts long and sounds good to him.
I will be surprised if its 15 Watts plate dissipation. At such high dissipations, near the maximum dissipation rating, the 2A3 always sounds stressed there, because they are stressed, thermally stressed.
Post up here his response.
If anyone has to run the 2A3 that hard, for it to sound good, a DIYer likely has multiple problems elsewhere in his DIY gem / amp, typically in this order, power supply, wiring, layout, parts choices.
Be cool to hear Jac's response. Jeff Medwin
