do not use this version of the chipamp. It has problems that beginners are unaware of and have to ask why their amp blew up or their speaker was damaged.

Find an AC coupled version that has both the input filters fitted and uses all the National "optional" components.

The PSU shown looks like an early version of Carlos FM 3886 amplifier & PSU. Go and find his later versions. From memory they include all the missing components.

Yep, I just bought that kit about a week ago from chipamp.com. Should I change the schematic someway? I use 10k volume pot.
