Put in an order for a LD MKIII a couple days ago, and hopefully expecting it in sometime this week. Also wound up ordering some Mullard EF91 and Brimar EF92 tubes on ebay, based on recommendations in the tube-rolling thread. This'll be my first tube amp, so I wasn't too sure what the "right way to do it" was - I know the LD comes partially burned-in from the factory, but should I go ahead and put some time on it with the stock tubes, and then swap to the other sets?
LD MKIII burn-in with NOS tubes?

yes please do continue the burn-in with stock. i'd say 100+ hours. and do the same with the others. so that way u have a roughly estimate of the stock compared to the EF91/92 improved tubes.
oh be sure to put a variety of music into the unit with burning in just to cover your bases. and hey can double as burn-in for your headphones if its new. i did put some pink noise into it as well.
