I have a Welborne Labs linear regulated power supply rated at 12V3A for sale. 5' umbilical cord with 2.1mm DC plug included. I've done the following upgrades to it:
- All internal cabling replaced with cryogenically treated 18AWG solid core 4N copper with cotton insulation.
- Stock IEC inlet replaced with cryogenically treated Furutech FI-10(G)
- Stock fuse replaced with AMR Gold Fuse
- All contacts treated with Deoxit Gold
