[Amps] Microwave oven transformer

[Hsu]

   I just discuss with a microwave oven transformer manufacturer about his pruducts, he told me he can make transformer for me as I want in very low price.We disscuss about transformer's working  temperature, he told me that the xformer using  specal insulated  material,so the working  temperature  usually  between 150-170 degree Celsius, certainly, it needs force air cooled.The CCS rating of 1000W uwave oven's HV transformer is 1450W,weight 11-12 pounds,I want  add filament coil  reach 12.6V,so I can use it in 2xGI-7B amplifier.Certainly I must remove the magentic shunt, I only use one  transformer, but I have seen somebody use a pair transformer and  full wave rectifier  as  PS of a pair GI-7B's amplifier.  Maybe the tranformer only need one weight 11-12 pounds transformer, Is that right?
