I have constructed a gain clone type amp based on the LM3886 chip from Texas Instruments. I have wired it using some available 16 gauge stranded wire. It is powered by a centertapped 34 volt (68 volt total) transformer that is fused by a 2 amp fuse. It is working with no issues however I would like to rewire the thing with smaller wire to clean it up. Would you please advise me as to the minimum size and what the wire is called if there is a particular type of trade name. Project wire is unavailable to me where I live. The auction site works best for service and inexpensive shipping. Thank you John.
