Finally at 345 hours of burn in I have all my ducks in a row to perform the afore-mentioned modifications. I parted some .250" thick 7075 billet aluminum discs off some 1" rod stock on the lathe. Will mount them to the DS chassis floor with JB Weld at the new coupling feet location. Already pre-drilled and tapped them for #6-32 brass threaded adapters that are 1/4X20TPI at opposite end for threading into the Rollerblock top cup. Once cured after 24 hours I’ll be able to get the Rollerblocks neatly installed .010" inset from the drop-down case protrusions that are just outside the OEM rubber feet. I’m looking forward to significant improvement once the fuses and coupling feet are installed! Not to mention it will now match every other component fuse and coupling feet in my system! If all goes according to plan today/tomorrow I’ll top the 500 hour burn on the DS a week from tomorrow, Sunday. May 3rd. I’m swapping a used 1A SR Red T fuse from the 12V ULN power supply I use with my DSPeaker Anti-Mode I seldom use so no need to break a new one in. Threw the new SR Red into the DSPeaker. Sometimes ya just get lucky! Enough rambling… time to put the DS on ‘stilts’ and get after it!
Update Pre-drilling and tapping the discs was a bad idea due to some clearance issues with the aluminum angle that holds the walls/floor together not being equi-distant at their ends (shoulda seen that one coming!). Good thing I parted an additional 20 or so discs that haven’t been pre-drilled/tapped! I’ll just epoxy them to the floor overnight and tomorrow drill thru the DirectStream floor & discs simultaneously after epoxy cures then tap their threads. Fuse has been replaced and that’s an altogether easy project!
