Quote:Tantalum capacitors do not age or deform like electrolytics do so there is no issue with that and the logic board is mostly tantalums. The cap that blew is on the 18v rail to the 5v regulator and was only rated 25v. A little close for comfort in my opinion since it runs off an unregulated power supply. Should have been a 35v cap, which it is now.I used to do electronic service and repair and I can count the fail tantalum on one hand.Hopefully I will get a break in the clouds later this week.
George You know you're getting on when the equipment you farmed with is showing up as suburban lawn ornaments.

Quote:I did find a site where they list the ones that need to be replaced. I will do that tonight. Also thinking of replacing the 7805 with a little DC/DC converter. More efficient, less heat. Or is the hand control supposed to do double duty as a hand warmer?
Quote: George. one of the leg ears broke off. I did successfully weld it back up, but the tripod is in such poor condition that I dont know if I will bother using it. It was stored outside.
