eb104.13

  • EB104 amplifier board ordered from Communications Concepts, including 4x MRF150
  • Omron 12V Relays ordered from Ebay – used for TR switching and filter selection
  • Toroids and accessories orderd from Amidon
  • Large heatsink gotten from my father, TF3T
  • 1200VA toroid transformer was bought in my trip to Shanghai – loong story there!
  • Going to order some silver-dipped MICA capacitors and PIC MCU + filter capacitors from www.mouser.com

Still need:

  • Copper spreader
  • 12v cooling fans
  • Hardware
  • Heatsink for the PSU – asking locally

Next thing is to build the case

Going to build it from Aluminium parts available locally, have made some sketches in AutoCad, but it’s hard to draw it exactly as I don’t have all the components in hand, and don’t know the exact dimensions of some of the components.
