[QUOTE="handsome, post: 946756, member: 772"] What is your required HT voltage? 200V seems a bit low and 200mA seems a bit high for a preamp. 6.3V means you plan on using AC heaters, 3A seems a bit high for a preamp. [b]Don't[/b] order a transformer until you are 100% sure of your requirements. Design your device first. Double check all your voltages. THEN design the power supply (it will need some filtering at least). Then you can order a trafo. Remember if you get the trafo requirements wrong there is very little to zero chance anyone will buy it off you. Start with the design, end with spending money. [/QUOTE]
