It seems some 390k resistors have found there way into my 390 Ohm box. I don't think it were a lot of them, but I don't really know (no clue as to how it happened). There is a chance you might have received a board that contains the wrong resistor value. If your IR printing works, you have the correct resistor. If you don't use IR printing, it does not matter to you. But if you have tried printing and it did not work, please contact me.
Sorry about this,
Harald
