Somebody had blown the FET's one or more times including
me once. The single sided hand me down PC board was in bad
shape. Don't get me wrong I greatly appreciate the gift.
It is not going flying but I want it working
for R&D purposes.
I am now in my bragging mode. I thought I was too old
to do this sort of stuff so here are some pictures
of my "fix" which I am real proud of :)
The key is to have the right tools.
Two more FET's to go.

Nice job Paul, reminds me of my production test tech days.

I have a little FET inverter drive for the mist pumps on our
transmission dyno in pieces on my bench today. Hopefully
I can still get the FETS.

Thanks Craig.
This company seems to have some obsolete chips.

I cannot find out where in the world the warehouse
is but it is a week away by ship :) I'll know
more in a week (if I get delivery) as I could not find
some IR2155 self oscillating half bridge drivers in the
states and they claimed to have them.
BTW I added sockets for the FET's in case I blow them
again. I'll also had sockets for the IR2155's.
