I was making a slayer exciter recently and I ran out of copper while winding the secondary up, with a goal of 1300 turns.. I ran out of Cu wire, but I do have a lot of aluminium(37 AWG) wire(enamelled) laying around... Can I use that instead? My guess is it should work, although aluminium is a bit less conductive, but I need some help from experts or anyone who has better knowledge about all this stuff I do have a 18 AWG copper coil for the primary ready (4 windings).
P.S I'm powering the exciter with a 40V DC input, using a MJE3055T power transistor/TIP41C.. the circuit is pretty basic..
