after blowing a power transformer in my DRRI, i had my amp tech replace all the iron with mercury magnetics transformers. then, while he was in there, i figured, why not have him just replace everything... so i bought the hoffman AB763 board from the airtight garage. a year later, and after a thorough workout, i can honestly say that my amp is now one of the best sounding, most touch sensitive amps i have ever played through. i can't recommend this board enough.
