Review on 🔥 Awxlumv Large Aluminum Heatsink: Efficient Cooling for IC Module, PC Computer, Led, PCB - 7.87 x 2.71x 1.41 inch / 200 x 69 x 36 mm by Dan Barrett

Easy to machine. I used it in a resistor box I built using four 100W resistors that takes 96.25% of the load from my 50W Marshall ORI50H and converts it to heat. It's a Marshall, a resistive box, a 100WL pad pad, then a Marshall 25th Anniversary 2556AV tilted box and two Celestion Vintage 30's. The resistive box should have allowed me to crank the Marshall ORI50H at full volume, but being able to comfortably talk through fully loaded JJ EL34s with an attenuator closer to the mid-range. Without the heatsinks, the temperature of the resistor block was close to 400°F, which was too hot for the electrical components and a risk of burning the tolex and me. On coolers positioned with vertically aligned fins for natural aspiration, the resistance box runs below about 135°F (with fins around 130°F), with the L-Pad dampened over the midrange as opposed to just barely raised .
