After a few weeks the fuse in one of my racks blew again.
I checked the modules, switched back the only two that had changed places in the rack for
good luck and blew another one upon power up.

Aside from two modules being switched in the bottom row with each other, nothing has
been added to this rack since the 198 came out. It has neer acted uo or been a problem.

I spoke to Analog Haven who were very nice, informed and supportive and they made
some suggestions but I am still at a loss.

Should I replace the power supply
Can I do this myself
Should I just buy a lot of fuses and take modules and plug them in 1 by 1 unitl something
blows

Help,
