I recently built the Elekit TU-8600R-VK with Lundahl OPT's and TKD pot.
I'm running Gold Lion PX300B, Tele 12AX7 and RCA Cleartop 12AU7.
It is sublime!!! Amazing amp and would costs $1800 for the upgraded kit, a few hundred more for the tubes I mentioned, or you can go with EML or Elrog 300B within your $3000 budget.
Not that it matters too much but Herb Reichart reviewed it for Stereophile and compared it to $20K amps, landing into the list of recommended components.
