Hello,

Relatively new here. I'm mostly a guitar/bass tube amp tech/builder but dabble in HIFI. I'm building a CFA2/3 (not sure if I'll add a bal/unbal board eventually). Dual Mono, 2x GRLV, 4x CFA2 boards, and maybe a bal/unbal down the road. I plan to use this with my LCD-2's (orig), and my desk monitors via added speaker outs. I have all the components on hand but the chassis so far.

Details: Dissipante 3U chassis. Mounting boards directly to heatsink.
  • 2x Antek 100VA 30V trafos with steel covers
  • MUR820 Ultra Fast diodes on daughterboards vs standard GBU4 package rectifiers for GRLV boards
  • Goldpoint quad/balanced stepped attenuator
  • KG Headphone Protector Board
  • Options for Bal and SE in
  • Bal and Unbal outs (unbal out only works with se ins in CFA2 mode)
  • Dale CMF 1% resistors throughout

Here's what I have drawn up so far for Front/Rear panels I'm having made at Modushop, as well as internal layout plan thus far.

Many Thanks to the infamous Dukei/Miroslav and Pars from HeadCase for guidance, arteom from diyaudio for generously supplying boards, and of course Kevin Gilmore for this awesome design.

Will update as I go. Any input is welcome!
