I received my KT77's from eurotubes yesterday (Saturday) and I've got a cd running through them now and for the next couple of hours to give them a good burn-in. I got a full re-tube kit with a lower gain JJ ECC 832 for V1 and ECC83s for the other 2 pre's. This amp has more than enough gain so I wanted to hear how it sounds with the ECC832. Plus my Crunch Box has a monstrous amount of gain available. To be continued.................
