| HBR 14 coils conversion to toroidal coils | cathoderay | on 27/6/14 |
| Hi, I have studied the tube HBR 14 receiver for several months now, and I am gathering together the required parts. I have managed to obtain the IF coils from e-bay. I now turn my attention to the RF and osc coil design. I wanted to change my design to cover the whole HF 1.7-30MHz. And I wanted to use toroidal coils for the RF and Osc coils. Is there a resource around that will enable me to be able to design the RF transformers, using toroidal cores? I would want to switch these in, not use plug in coils. Possibly using reed relays. Does anyone have a view on any of my plans? I would be pleased to hear from anyone who has done similar mad things. |
