Here's what I'm working on...
Designed to be cheap Using all parts found at Mouser, digikey, etc.
API 500 Form factor
2 switched freq. On the high and low bands
6 switched freq. using Lorlin (or what ever you want) on the mid
Hi/Lo Q on the mids
Bypass All and you can switch out the mid on the seventh position to leave just the shelfs in.
Fastron inductors (thanks NYD) on the 5 higher bands
Xicon/Mouser Trafo/Inductor (thanks again Dave) or Wilco BSL's on the Lowest mid and LF bands
Input can be ina134 or Edcor PC10k/10k (I haven't tested the Edcor'syet)
Output Edcor PC600/600 (again I haven't test the PC series yet. They might suck)
Op amp can be you Lab variety Discrete/Hybrid/whatever 990 footprint or your garden variety NE5534.
The pots will have to be Bourne 91 series, or the board will not fit into the rack right.
That's about it. It's still in the conceptual stage right now. The hardest part is the mechanical aspect. I got to make sure this puppy is going to fit right.
Here is a quick mock up of the face plate. The holes are close, but I want to get it down to .000" if possible. Don't mind the engraving. It will change. Like I said, quick mock up.
Cheers,
