The 208 Hub

The Hub makes it possible to plug 3 cards side-by-side to a 208 or Easel, or even up to 6 thanks the rear edge connector of the ToolBox series cards.
  • 3mm thick 4-layer PCB for best stability and rigidity
  • M/F stackable gold plated banana plugs to access the panel banana sockets used for mounting
  • Gold plated transfer card
  • Easy plug and play design
  • Jumpers to use the 208/Easel's +/- 15V rails or the optional +/-15V PSU powered from 9 to 36V DC (the common 12V Cincon external block works fine) to relieve the 208/Easel's own PSU if more than 3 cards are used together
  • Works with any existing card or expander

DIY PCBs only are available for now. Pre-built Hubs should be available in June.

BEMI / Buchla USA Easels and original 70s 208, 208p and 208r have a different banana sockets placements, so the Hub is available in 2 versions, please select the one that fits your own Easel or 208.
