Well this came as a bit of a surprise to me today. We ordered 2 Power transformers, 2 chokes and 2 SE Output from the Hammond Transformers in the UK. They all arrived okay last week in their Black Shrouds. We set about spraying the End Bells a different colour. We tested all of the them before putting them onto a Chassis. After about 2 minutes one of the Power Transformers started to Smoke. Long story short it is TOAST. On contacting the supplier we were told that because we had removed (the End Bells to paint them) that the Warranty was now Invalid (What ????????) That's a bit like saying that the warranty is now revoked because you used the product, what kind of BS is this.....please ALL be aware.
