Not necessarily. I tried to rebuild the blu/von erl pod. A German guy on youtube can rebuild it, but there was no chance I could do it. Tiny, tiny bits of brass with little slots in them you had to bend, take apart and wedge a coil in between. Even if I’d managed to do one, it wouldn’t have been an option to do in the long term. I’m going to try the air once this pod is done, I think this could be easier mostly because it’a better made and looks like there’s is a bit more space. But don’t know yet.
