[sdiy] sn7413n schmitt trigger

[Miketina]

Hi everyone
Has anybody built circuits from the old 70s Wireless World synthesiser? There is a chip in the VCO which is sn7413n schmitt trigger - can I use a normal 74LS13 dual schmitt trigger for this purpose? The rest of the parts are very easy to get so it would be a good VCO to build if this problem is solved. Have a look at the schematics if you have it. Would appreciate any help.
