Thanks for your reply

No, it is not shorted, only in appearance

top right next to 7660 it appears that the resistor is shorting to the link ? maybe just the camera angle though?

Hello

I appreciate your help
When I saw that there was someone who said that I had done it and it worked ... I was encouraged to do it but I did not have that luck

Thanks in advance

Some pictures please..

Dear partners:

I'm new to the forum, I decided to make the barracuda project
after a failed first attempt I decided to make the plate again
In this second untill ..... the ICL7660 is heated after connecting the battery
For more than reviewing everything I am not able to know the reason
Can someone guide me?

Thanks in advance

I do not see in any datasheet ucc27321 with four legs. Either DIP8 or SMD8 8 pin.

A quick question about where you have reliable source for 2N5485, MPF102, PN4391,PN4393 or 2SK170? I think these are the last elements i need. Got almost everything from Farnel but they have no stock of the above. Thanks.
