Thanks i like to sink the drivers over 1.8A and copper to copper well it can't be bad. 3200 to 3300 mW's isn't to bad and stable for the 2-18350's.
Lots of ribs on the sink to dissipate some excess heat to.. thank you pal ..hey I try ..
Thank you and when you handle it you can feel the weight and heft of the copper sink and knob. Duty cycle for this is unbelievable over two minutes and only a little warm not much. Had a great time building it.
Hi made a mistake sorry, its a NDB7875/9MM Diode ..
