Re: Caps in resonant supplies Hello Sailors,
Don't remember if I posted this already. If you replace the cap in a resonant layout supply... be sure to replace it with the original value. If you use a larger or different value the end results in some layouts can be quite the large bang... There is a serious reason why a specific x-value of cap is used. cheers, skipp > "Bill McLure" <[EMAIL PROTECTED]> wrote: > > I'm suspecting the ferro cap after looking at it. It seems to have some oily residue on the top of the can so maybe it has been leaking. I'm unable to check capacitance but I did pull the leads of and check with my DMM on ohm range and its not shorted. It will start to charge up on the higher range but then again unknown capacitance. Anyone know where I can get a new cap like this?? > > Bill... > > -----Original message----- > From: "Jeff DePolo" [EMAIL PROTECTED] > Date: Mon, 05 Feb 2007 22:12:09 -0800 > To: Repeater-Builder@yahoogroups.com > Subject: RE: [Spam] RE: [Repeater-Builder] Mastr II Station Power Supply Problem? > > > > > Pull out the ferro cap and test it. > > > > Or alternatively, take the cap out, tape up the leads that went to it, and > > fire up the supply again and see if you get the same amount of sag under > > load.
