I uploaded the files for corrected Woody layout. Check my site.
Thanks to both you and Bill. Anyone built a working unit yet?
I didn't built it yet, but I'm planning to start to build it in Monday.
I assume you mean Bill Lawrence, but I haven't had any luck getting mine to work. Something still wrong with Marcos's layout. It has 2 anode sides of the diodes connecting to pin 10 of IC2.
I'm uploading the correct version of the image/eagle file.
I think I've detected something wrong with the Bill LAwrence PCB.
The filter cap on the TL072's pins 6/7 is not in parallel with the 22K resistor..
Maybe I'm wrong.Please check.

You're right, there is this error. Hey Bill (Lawrence), could you correct the layout?
Thanks Aharon,
I missed that on my layout also. I'll fix it tonight and see if it works.
No problem will make the correction
Thanks
BILL
that was the problem. it works now but I dont have time right now to run it thru the ringers.
still has a squeal when the volume is all the way up butturn it back a bit and it goes away.
my batteries are probably weak also.
sounds sorta acousticy
just listened to Mark's sound clip and it doesn't have near the ringyness of his.
I uploaded the correct layouts drawed by Bill Lawrence, the Powerpoint and ExpressPCB files.
The Power Point seems to still have the error,maybe you uploaded the same old one by mistake?.
Aharon
It looks likethe old one to me.
Will need to recheck
I know we have been having problems with our server.
Don't use the files - they are the old ones. There seems to be a problem and I'll fix it -
BILL
by shorting across the 100pf cap below the diodes I get rid of the squealing.
Anybody have a clue?
