Its not an Omron then? I have used one before, in a project for the tv station, never gave a hint of trouble. But I know nothing about a HED 8950. I'll see if I can find something about it on the web. Looks like it may be an obsoleted model. Or, less of a chance, too new for their catalog. It is not listed on the makers site. So my best idea is to get an Omron from Ebay. A dollar or so more than a $20 bill, maybe $25 with shipping from someplace in the USA. > > The 7i42TA's are that.

If you only fed it 5 volts on the red wire, and it has now failed, its duff, send it back. OTOH, if its NOS and died, its a good chance the next one will be the same age and well up the far end of the famous bathtub curve. I'd vote with my card, and get the Omron. Oh, and if somebody is taking up a collection to round up this Murphy guy... It sucks just when progress was being made.
