Local LLM for electronics design work?

Another hobby is working on electronics projects ranging from low-voltage control and signal processing to HV tube amp circuits. I design and simulate in LTspice before prototyping. I often use the cloud models for design help; they're great at architecture and topology, but when you get down to the details they start to lose the thread, and in the worst case, start hallucinating and giving patently bad guidance. Qwen3.6 is similar; t gets the big picture fine, but gets lost in the details, *especially* when troubleshooting.
