“Great transformer, just what I was after. Quality seems spot on and the voltages are perfect for my valve amp build (Fender Harvard). It’s getting harder to find decent transformers with 5v taps for rectifiers that don’t cost the earth or need to be ordered from the USA.”

“I have recently purchased one of your mains transformers for a project, whilst I have not tested it yet, going by the quality of construction I do not think I will worry about the performance of this product, it is superbly made and I look forward to using it.”
