I have to, sadly, report after a decade of faithful service my original DP24 has passed. On THE most important recording session of recent times, I had to resort to my laptop and DAW. Talk about complicated! Seems after reading up it may be the PCB Tascam E95439310A. After a trip down to London from Peterborough I plugged the PSU in and pressed/held the on button . . . . .blank. I will open her up to check obvious connections, but I fear the worse. Can't afford the part, so can't afford a new unit. Now what, I wonder?
