Wire size and type for gain clone type amp?

[JohnM24018]

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.

never heard of the term before

now that I know what it is, nothing special

is it really worth the effort ?? seriously ?

there's an old saying ... " if it aint broke, don't fix it"For only a couple of amps for each rail, you could easily drop down to 20SWG, I wouldn't go any smaller

look up insulated hook-up wireDave

Keep the 16ga to pins 1,3,4,5, the power supply, and the speaker connectors. The rest can be whatever is easy to get and work with. I usually use 22ga, stranded if there will be vibration or flexing in use or solid otherwise. I find the solid a little easier to work with. Even 30ga would be OK If you like working with tiny wire.

If you have good speakers needing more than 6 feet (2meters) of wire, you may get better sound using 12ga to them.

Decide what actual spec you need from this amplifier before you spend more time on it. That's the basis of all 'good' Engineering.
