Thanks Mike for the correction, I agree it is over voltage with the crowbar
circuit. BTW, I have a model 280 PS I keep for standby. If memory serves
me(which isn't much these days!), the Model 280 was the PS for the Delta
and the low end priced PS for the Omni-C. My 280 PS works great, with no
hicups. I don't know why I keep it, but you know when it has the TT logo it
hard to part with!

  The purpose of a crowbar is to shut the supply down
