Sv: Re: [sdiy] Harry Bbd and LF13331

[Daniel Araya]

Hi, 

I'm restoring the EMS Buchla system in Stockholm and i'm using Marks
recommendation of DG202's instead of LF13331's.
I'm changing the working LF13331 too, they seem to be sensitive to
powersupply fluctuations etc. so it's better to be safe.
You have to change the pinout a bit to use the DG202. I us an ic socket
and bend three legs of the DG202 and solder a pair of jumpers.
I made a rought sketch: www.icb.se//araya/pics/synths/lf13331sub.bmp

Be careful of signal level, one resistance and switch speed.  I
recomend 
DG200 series or LTC202 to replace them. Which require no adaptation.
