Hey guys,

I've been mucking around with this DPDT mini-toggle switch and I think I've come up with a way to make it work with
my BSIAB2 (doing a cap switch on C8, between 0.1uF and 1.0uF).  Thought I'd share the results:
   
    (000)     < 0.1 uF cap
     |  |       < cap legs
     ll  ll       < top lugs (attached to 0.1 uF cap legs)
     ll  ll       <centre lugs (each lug attached to it's respective hole on circuit board)
     ll  ll       <lower lugs (attached to 1.0 uF cap)
     |  |       < cap legs
    (000)     < 1.0 uF cap

Pretty basic ascii, but I wanted it posted for noobs like me.  :)  It works with resistors, too.  I measured it
with my Digital Multi Meter, but if anything is incorrect please don't hesitate to say.

Cheers all
Phil

You can do it with just a SPDT too, although admittedly the DPDT ends up a bit neater...

Yup that's right.  I just finished it and tried it...pretty subtle...but it was only on the tiny solid state practice amp.  Will post
results from the Triple XXX tomorrow  :)
