I was taking inventory of the parts for the MU524 I just received and there were only two OP2134 in the kit...and there was a third IC next to it which is a THAT1246.
Checking the spec sheets, it doesn't look like the THAT1246 would be a pin-for-pin equivalent replacement for an OP2134.
Does Sound Skulptor substitute a THAT1246 for a OP2134 when low on OP2134?
If that's a mistake, may I get a replacement OP2134?
Thank You,
Ed
