Re: When should a power supply be declared Perma-Dead?

Hey General.

If you're actually willing to open up the Power Supply case and do a little 
soldering I might have something that could help you.

When we produce our 200w IIgs Power Supply we 'gut' the old power board from 
the case.  Since we offer these boards to the public for free instead of 
throwing them away, you could order a few and replace the defective one in 
your case.

Here's the link: http://www.gse-reactive.com/product_info.php?products_id=69

Just pay for the shipping and I'll send as may as you'd like!  Makes a nice 
bench power supply too.

Hope that helps.
