Re: Enclosure #parts

Re: Enclosure #parts
Jack, I used the large cake from Harbor Freight and it has worked well.? It's not exactly watertight anymore after several revisions to my grand plan, but it works.? I used a Lexan sheet from the

Re: Easy, Inexpensive Cooling Fan, Excelway Case
If the fan is generating RF noise, ?that can often be cured but putting ferrite beads on both of the leads as close to the body of the fan as practical. RF has a way of sneaking around on DC power

Re: Easy, Inexpensive Cooling Fan, Excelway Case
The fan is aurally quiet enough, but the case resonates a tad with it, so you can hear it.? If I wanted to do some vibration isolation and case panel damping work I could probably make it

I'm thinking about using an Apache case from Harbor Freight. However, I need a way to cool the PA's with some kind of fan, but without destroying the watertight nature of the case. I'm going to use a
