My next task is choosing some wire. I'd like to use different colors to signify heaters, B+, signal wires, etc. rather than having the chassis filled with with all black wire that I used on my prototype. This part is easy - there are "standard" color charts floating around for wire color in tube amps. It also seems there is a preference for solid core wire (20g) over stranded and the logic that solid core wires tend to stay put makes good sense to me.
So, this leaves me with what I consider to be an aesthetic choice for wire: teflon or cloth-over-pvc for the jacket. To me, the cloth seems potentially more in line with "vintage" tube gear kind of look-and-feel. With the options that I'm looking at, prices are close enough for either type to be considered equal, so price isn't really a decision factor. The only thing that I can think of is that teflon might be easier and cleaner to work with than cloth.
Is there something that I am missing that might suggest that this is not strictly an aesthetic issue?
Any impressions or experiences that might favor the use of either teflon or cloth? Any value in choosing 18g instead of 20g?
Thank you!
