[QUOTE="WillemJonker, post: 1118655, member: 25516"] Hi Karel , thanks for sharing the design , I have recently simulated a SE OPT for EL84 , EI96 on 32 x32 mm bobbin just for learning and understanding Dissident As this is my first attempt to learn how to wind an OPT , I want to keep things as easy as possible , so my questions is more in general to get broad guidelines 1) What would be a safe figure for Pri L (Hy). Obviously the higher the better the bass , but to get to say 40 H , is a lot of copper , and do influence HF response 2) Talking about HF response , I tried to keep the winding plan as easy as possible. If I use one primary and one secondary , I get 29 Hz to 22 Khz , with 14 Hy Pri L. So I guess my question is why all the complicated interleaving , what am I missing ? 3) When does one use bifilar winding. Reason for asking is , can I wind primary and secondary together in bifilar fasion to safe time , keeping in mind the secondary will only be 73 turns bifilar with primary , rest will all be primary I have attached the simulation for reference , [ATTACH type="full"]16283[/ATTACH] [/QUOTE]
