on the vtl deluxe there is only 5 tubes to replace versus 8 for the super del; 4 phono / 2 line /2 12at7.
is your rogue 99 an integrated or single amp?
my integrated uses 2 input signal 12au7 tubes and 6 el34 power output tubes.the signals valves are most crucial.
In the deluxe if you select the phono stage section the 2 12ax7 will be most important/if selecting cd line stage the 2 12au7 will play the main role and the last tube the lone 12at7 is the driver tube which power both (always in play).
the superdeluxe is a real departure from the deluxe,way more balance, open,airier at least from the deluxe I've owned, no comparison,also confirmed what VTL described at that time.
in their original black color.
These are scarI might put mine for sell since I do not need it anymore (just bought my unison research integrated)and thinking to buy a pure phono preamp that my friend is going to let me test.
my unit is mint/unmodified/no scratch and the top case on the separate power supply / main unit has been beautifully professionally repainted in a dark grey color leaving the front plates ce and in demand,
The last one I saw on auction on this site went for $700 +
If your friend uses the deluxe what do you use yourself for preamp right now assuming your rogue is not integrated?
