Maybe SS amp builders can learn something from them rather than
dismiss them because they are not complex enough .

**THEY ARE COMPLEX. Very complex. It's just that from the outside they
appear to be simple. It is their simplicity and low which makes them
attractive to low end amplifier manufacturers. This is why you find them
in $199.00 all in one systems. Cheap, easy to use and hard to destroy.

Indeed.

The advantage of using an IC as in the gainclone is that all the complexity
is 'hidden' inside one small pack with just a few leads - making it easy
for someone who lacks experience to use it to make an amp.

The disadvantage of using an IC as in the gainclone is that all the
complexity is 'hidden' inside one small pack with just a few leads - thus
making any alteration of the complex circuit details inaccessible to an
experienced or knowledgeable designer who might want to alter details to
get improved performance or avoid some of the limitations of the IC.


Slainte,
