These are new Edcor GSXE 5K-8ohm transformers. Did i get a bad output transformer from Edcor?
I just received new transformers from Edcor last week. Including a pair of GXSE 5k-8s. On Monday I received an email from Phyllis at Edcor indicating there may be a problem with the transformers. I tested them, and sure enough, there was a problem. Edcor shipped my replacement yesterday at no charge. I recommend you test the transformers and see if they are OK.
They said that the primary windings are out of phase. They pass a simple DC resistance check, but have little to no output when driven by an ac signal.
