Wire size and type for gain clone type amp?

Click For Summary
A user has built a gain clone amplifier using the LM3886 chip and 16 gauge stranded wire, powered by a 34-volt center-tapped transformer. They seek advice on rewiring with smaller wire for aesthetic purposes, as project wire is unavailable locally. Responses suggest that while the current setup works fine, using 20 SWG wire could suffice, with recommendations to keep 16 gauge for critical connections like power supply and speaker connectors. Some participants question the necessity of rewiring if the amplifier functions well, emphasizing the importance of understanding the amplifier's specifications before making changes. Overall, the discussion highlights considerations for wire size and the balance between performance and aesthetics in audio projects.

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.
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
