JS:
You might want to look into replacing the stock 6DJ8 and EF86s in the Repro. The best I've found are the Tele EF806S and Tele E88CC. They'll give you a cleaner, more transparent sound with more sense of space and attack and a bit better bass. If you want a little warmer, not quite as extended, but with a little more mids, you might want to try an Amperex E188CC/7308 and Mullard 10M ECC88. There are a few other tube combos but despite having the tubes around, haven't tried them yet.
