[sdiy] DG201 vs LF13331

If they are being used as analog switches I'd suspect they might work fine, but the LF part number
seems like a National Semiconductor part, and there were some where the 'control' signal was tied directly
to the gate of an internal FET and they could be used as voltage controlled resistors. I don't put it past
Don Buchla to have used a part like that... 

Is there a link to the schematic you're talking about ?

I was wondering, since I have a lot of DG201's, if they would 
substitute well in a circuit that called for LF13331's, such as the 
Buchla 292C Lowpass Gate. I could look at datasheets I suppose but I 
don't think I have one for the LF13331.
