[SADXA] Lightning Bit Me

[WD7F - John]

Wes, thanks a bunch.  It was a bit different in that the spacing where it
screws to the filter caps is a bit narrower.  I jury rigged that.  Then the
driver transistor on mine was on the main chassis.  The one you gave me had
that transistor on the regulator board.  That was good.  Anyway, I have it
up and running at 3/4 power.  I managed to find 4  3771's in my junk and
scrounged one from K7IOU.  The rest were smoked.  Ordered new ones on the
web.  Ain't paying $8.00 to Elliots.

I appreciate the help.
John

They're pretty straightforward power supplies.  I converted one to a "smart"

battery charger.  So I removed the regulator circuit board and basically
just used the raw DC and pass transistors with a new charge controller
board.  I have the old regulator board that you are welcome to.

Since the fuse isn't blown, you probably have some DC and just need the
lower power (and more sensitive) electronics.
