Transformer winding - All transformers are simple to wind, wire diameter for transformers T1 and T2 isn’t critical. For T3 don’t be tempted to greatly increase the diameter of wire although the core holes would allow it, using a wire significantly thicker increases its self capacitance affecting the transformer wide band performance.
The one turn primary of T4 and T5 can be made froma piece of braid removed from RG58 or similar coax, for the secondary winding use ***** PVC covered hook up wire. ***** Use the heaviest type that will pass through the cores.
