Tung Sol reissue 6v6 sounds really good in the VK75SE. Recently I've been using 6SN7EH pretty much everywhere, except for Raytheon or Sylvania Chrome Top in the single position in my preamp that has the greatest effect on system tonality. But there have also been good forum reports on Tung Sol reissue 6SN7.

IME, V-Cap TFTF coupling caps & replacement of internal IC takes the BAT amp much further than any tube rolling & is simple to DIY.

Consider at some point opening up those 150SEs and trying V-Cap TFTF coupling caps, as well as better wires to replace the 2' lengths of $.40/ft Belden IC-- two significant upgrades to your impressive system.
