Hakko FR-803B schematic / transformer specs

[eduaqa]

Does anyone have the schematic for Hakko FR-803B? My transformer burned and the original one is to hard to find and too expensive when found.
I would like to have a look on the schematic for the voltage on the secondary, I believe a generic transformer will works good and will costs 1/10 of the price of the original one.
If someone also have a Hakko FR-803B and can measure the voltage on the secondary and post back I really appreciate.
