I'm glad you wrote back 'cause I meant to say something else and forgot. Your writing reminded me to tell you to check everything from time to time. I know you like to put the power to these things. I do too, and I run a Crown Microtech 2400 so I can really push 'em hard.I have the resistor banks mounted physically near a plastic plate used for my connector panel. The heat from the resistors has melted and deformed the plate. Sometimes I think about replacing it, but it is not really a problem so I don't. But I'm just saying that even when you build-up large blocks of resistors like this, they'll still get pretty hot when you put the power to them. So check them out from time to time.
