Ive used a few knock out boxes for projects over the years , plastic and metal
There avaialable from any electrical retail outlet and blank front panels come in a variety of metal finishes .
As either a chassis for a small preamp project or maybe to help screen a toroid on a larger chassis there perfect .
They come in a variety of sizes and the knock outs are more or less ready for mounting up tube sockets and XLR's in what ever orientation suits your build ,
You can hard wire up an idea in no time at all on tag strips , theres plenty of pre drilled holes , you also get a riveted brass grounding terminal .
Ok its never going to win any beauty contests but you can prototype an idea very quickly and cheaply and have good screening
If its just a preamp module that sits in a rack it doesnt need to look the pigs knickers , utillitarian will do just fine .
