1w amp schematic
« on: July 09, 2018, 02:58:04 PM »
I am going to try this little amp out. I don't see a volume pot. As a beginner, I'm not sure where it should go. Any suggestions would be greatly appreciated.
Thanks.

IC pinout is different, but it looks similar to the Ruby practice amp at RunOffGroove. In your schematic, replace R3 with a pot like you see in the Ruby schematic.

Thats the punch amp from over at diystompboxes forum. 

The IC in the schematic doesn't have a volume control, but you can replace the IC with a TDA7052A.  the "A" adds the volume control.  I think it connects to one of the pins to of the ic to ground but im fairly certain the datasheet shows you.

Or i could just check my own schematic for the chime amp :P
