Thanks Martin! Yes I have two remaining. Not kits though, since I had the whole board professionally assembled (each board has 120+ discrete transistors!). I’m willing to sell the set-up at cost since everything I’ve paid into it I consider sunk.
Everything finished to include the etched anodized aluminum, black acrylic, and standoffs would probably run around 300-350$ with shipping (tubes not included of course!). You don’t need eight to make the display work, it’ll take whatever you have, and you can set a soft limit in the code If anyone’s interested, just let me know On Sun, Mar 29, 2020 at 5:13 PM martin martin <[email protected]> wrote: > excellent work! > Kits avail? > > > > ~ > *[email protected] <[email protected]>* > > > On Sun, Mar 29, 2020 at 2:39 PM Mahdi Al Husseini <[email protected]> > wrote: > >> Thanks Kevin!
