Just to let you know, the 454 is firmly mounted in my workbench I finally got around to making. It's where I make all my junk come to life.... MUHAHAHAHA!!!!
Believe it or not, I haven't even come close to running out of BW on the 454A. It works just fine. I actually had to replace a couple of Electrolytics in the Power Supply last month... It was acting funny... perfectly good one minute... wandering all over the place the next. So, I hooked up my trusty "self-made" fet VOM I built from scratch (using Plywood as the face) and saw voltage rising and dropping...rising and dropping right after the filters on the PS.
Started looking at the components to see if they all had thier magic smoke in them still, sure enough 2 Caps had split covers. Apparently boiled at some point not to long ago. But put *expensive* replacements in... voila she good as new, No?
BTW, you should really look at the new "synthetic" Electrolyte companies are using in "premium" Caps. It smells terrible, even compared to arsenic based electrolyte. But, it is black and gooey. Supposedly has 5-10 times the insulating and cooling capability of standard electrolyte. Same size caps have high capacitance and higher volage ratings.
