Transformer with 3 secondaries

bondul · 15th July 2012, 01:16 PM

Hi, I am new in DIY and need help from all the experts in this forum

I am building a tube linestage. The PSU has a tube rectifier. It needs a transformer with 3 secondaries: 250V, 15V, and 6.3V. I have searched some transformer manufactures: edcor and hammond but cannot find it. I need to combine 2 transformers.

Could you suggest me what transformer that I can use? I am attaching scema that I am working on. The only different is I am using 115V as input (primary).

Thanks!
Bondul

You may want to use two transformers. One to supply the 250V and 6.3V and another to supply the 15V.

Thank You for quick reply! There are a lot of stuff in this HK store but I am looking for USA based store. The shipping for a heavy transformer seem same price as the transformer itself.

I am also open to advice on modifying the scematic so it works with any generic transformer.

Hi Frank,

That is my current plan now. I am looking for simpler alternative to combine them in one.
