In Reply to: Duelund 20 AWG Copper in Cotton/Oil is here posted by Jon L on October 24, 2020 at 11:10:11:
I have been trying the same Duelund 20g wire in my phono preamp the past few days, and I agree 100% with what JonL said. I would actually have used many of the same words to describe what I am hearing.My application is a bit different. So far I am using it only in the high-voltage B+ runs in my tube phono preamp. These carry 210v and 175v DC. In each case I replaced a Neotech 20g solid copper with Teflon insulation which was previously my go-to wire for B+ connections. It now looks like I will be rewiring some amps as well.
A hearty Thank You to "paco" for bringing this wire to our attention.
By the way, this particular Duelund wire is easy to strip. The cotton/oil insulation is different from that on the Duelund silver ribbon wire which was not easy at all to terminate.
I would be cautious about wire placement if the Duelund is carrying high voltage. I have no idea what the maximum voltage rating is for the cotton insulation and it is thinner than the used in the silver ribbon wires. In my case, I just made sure the high-voltage wires are not touching other wires or any metal parts inside the chassis.
