Hey, thanks for referencing the tut and enjoy building your mb-6582 - it still rocks every day and i hope TK still needs some time before mbsid v3 is released and Wilba makes a mb6582-v2 (Wilba, if you ever do this, i would love to see an integrated version with "external" filters and VCAs - a real virus killer ;-))
Ah, sorry for ot... Regarding the to-be-cut-nylon washers - these were the only ones i had available, if you have smaller ones, of course you do not need to cut them. (Mine were overlapping some solder pads). You may not need to use washers at all, the design with ~ 20 screws will hold very well, no need to tighten them much.
What i still would recommend is to use an LCD with a quicker update rate - mine is horrible - still looking for alternatives like oled/pled/vfd, but found nothing much yet.
Have fun!
Bye,
Hawkeye
