WTB: Cheap Soft start? A set/Pair?

azneinstein · 26th January 2011, 07:57 PM

I know these are simple circuits but I just don't want to risk damaging my "good" kits since I'm still very new. Just need a pair of soft starts for a set of monoblocks I'm putting together (just soldering ins and outs).

connexelectronic wants $19 each, hoping to spend a tiny less and get it sooner.

Will be used with a 250-300VA 115VAC 2x30 or 2x35A transformers, let me know if you need more info but it's for Greg's SKA150D boards.

Hopefully someone will have one collecting dust, thanks!

How about using one of these on each primary leg of your transformer? 3/$1.00 won't hurt too bad.

I saw those, and I also read this whole thing on whether it's safe to use just thermistors... and that site- which did feature several circuits of soft starts also had this whole thing on why it's bad to just use thermistors. It's one of the popular diy audio circuits site, I'll see if I can dig it up. bump!
