I built my test rig for the 1514a and found them all (10) to be putting out B- on pin 5 (output) except 1 that pulled down the pos & neg supplies (shorted).

So everyone beware of purchasing these 1514A chips on eBay, especially the one's in lots for cheap.

AFAIK they are the only non-Chinese source I've seen on eBay. But I will PM you the company name if you wish.
