Simmons analog Clap Trap - inside shot

Hello,

I am experimenting with the claptrap schematics but it has no parts list so I do not know what 1 of the IC's are. I was wondering if anyone that owns one of these rare clappers would be willing to send a shot of the top of the circuit board. I would be so grateful!

Hi,

I know this an old post, but are you still looking?

I've got a Claptrap here and I can pop the lid off. I'd be interested to see the schematics too...

This is an old thread but here's a shot of the curcuitboard of an old Musicaid Claptrap without humanize button.


And here with the names of the semiconductors

Next step would be to identify which semiconductor correspond to which in the schematic which can be found at Synfo:

I have made quite a thorough check now and I believe these are the correct references for the IC:s in the schematics.
However I'm not 100% sure and there are also some deviations between my older version of Claptrap and the one in the schematic.
Especially input pins on op-amps are not always identical. But I'm sure it's quite useful anyway.
