To darned long ago - you guys should throw another one!

I was thinking about having the bar/dot mode an option via a switch
Seems it may be a pain to figure out
John
Where's the pain? A DPDT switch?
jd
Yes was thinking about a pcb mounted DPDT switch for JB1,2,3 and 4 but what about JD1 and 2?
Cheers

OK for two channels you need a 4-pole switch, double throw. A bit less easy to find, yes.
Mouser gives 400 hits, like this one: PN42LESA02QE C&K Components Pushbutton Switches . $ 1.10 Or toggle types, hundreds.

What about JD1 and 2 are they shorted when JB1,2,3 and 4 are?

The 3916 data sheet should tell you which is connected to which in which mode.

The one thing that I did not like about the LM3196/5 is that the LEDs were not always hard on or off, but could appear to be fading on and off (i.e., those LEDs on the leading edge of the bar graph). I rather liked the fluorescent bar graph displays that were found in the Technics and Pioneer equipment of the time ('80s). Any options with regards to making the 3196 crcuit perform similarly?
