[sdiy] Glide circuit, how possible?

[harrybissell]

Well... I'll take the baton if no running shoes appear by magic on my
feet
(ref: a popular US track shoe ad)

Yes, the vactrol WILL work, the OTA would be a tough design.  Even the
vactrol
will be a little complex on the LED side, but not unworkable.

Did you see my "dithering" post ???
