schematic was not much to talk about. It is based on the Mapletree Super.
I modified it to AC heater cause it is cheaper and easiler. I used a pair Raphaelite output transformers instead of Hammond as it has higher impedance. so I can use a cap of lower value. They are cheaper and more choices.
I even try a pair of Mundorf Silver oil 4.7uf cap but I do not like the sound. I settled with a pair of Auricap.
Last night, I tried to change the cheap Raphaelite Output transformer to a pair of vintage Tango H-5S. I end up with smoke from the power supply. pretty scary!!!.
Anyone can tell me if I am using the right type of Tango tranformers?
