I'm not conscientious enough some days, and I connected a 1500 uF low impedence psu bypass cap in reverse on one of the rails. It blew a 6.3A fast primary fuse, then I of course replaced the fuse with whatever was on my desk (a 10A slo blo). Anyhow, the cap vented and spewed electrolyte everywhere. Makes me wish I was more careful, I connected the rectifiers and big caps with lots of care, but the local bypass I did in a hurry because I already had the dangerous and difficult parts done.
Any chance of peripheral damage. The supply lines are 31 volts, and the bridge rectifiers are 25 amp rated (and sinked to a huge aluminum plate), the transformer is 750 VA. Everything checks out and measures ok (diodes ok, can't check capacitance - too high for meter), and voltages measure fine now, but I am paranoid that I may have hurt my big caps, or the rectifier will now be on its way out, or the transformer insulation will now be melty and short any day now, or the transformer will sap up any electrolytic I didn't clean up and corrode and die. I even looked on wikipedia to see how corrosive the fluid is.
Perhaps I should take a break some day, but if I don't finish one task each day, my project will never go away.
Thanks,
Lee |
