Re-tube time for a BAT VK30. Advice please

It's time, the tubes are going sideways on me. You sure notice when your tubes are done eh? The VK30 uses (6) 6922 tubes. I've rolled tubes plenty over the years but I'd really like to avoid buying a bunch and experimenting. I like my sound laid back, the 'statics are plenty detailed enough. Musical taste is all over the map, Associated gear:

Oracle Delphi MkIV, SME345 Arm, Grado Reference Cartridge (marble base)

Lehmann Black Cube Phono Preamplifier

YBD CD Integre CD player (Brightstar base, with remote)

Magnum Dynalab FT11 tuner (Brightstar base)

Nakamichi RX-202 Cassette Deck

Grado RA-1 Headphone Amplifier

Balanced Audio Technology VK500 amplifier (with BATPAK)

Martin Logan Quest Z speakers

(2) 5' Synergistic Research AC Reference power cords (preamplifier, phono stage)

(1) YBA Diamond power cord (CD player)

(2) Harmonic Technology Pro AC11 power cords (amplifier)

(2) Maple Audio Works Ambiance interconnect (Black Cube, CDP)

(2) Transparent MusicLink interconnect cords (Tuner, Grado Headphone amp)

(2) Phoenix Gold RCA-Balanced interconnect cable (Nakamichi Deck)

Goertz Micropurl 25' Balanced interconnect (preamplifier to amplifier)

Transparent MusicWave 10' Bi-Wire speaker cables (spades)

I'd prefer to keep the re-tube cost reasonable, appreciate any and all suggestions. Thanks, Jeff
