HY, FRIENDS
HERE IN BRAZIL, I FOUND ONLY THE MN3008 IC. CAN I BUILD THE TONEPAD SMALLCLONE WHITH IT? WHAT CAN BE AFFECTED BY THIS CHANGING?
AND ABOUT THE IC PINOUT..... THE LEAD NUMBERS AREN´T SHOWED IN MN3008 DATASHEET. MAY YOU HELP ME?

You can use it, but you will need to increase the clock rate x2.  besides the obvious pinout differences (which you can compensate for with an adaptor plug) the 150pf cap tied to pin 1 of the 4047 will need to be dropped to 75pf to maintain the same delay range and produce the same sort of tone.
