I was asked by a member to build them a K272A, they had the parts but not the time
 
This is what happened
 

 
Loads of very clear instructions infact the board is so simple you really don't need instructions, its like painting by numbers
 

 
Filling the board was quick and easy
 

 
I wasn't keen on the small output caps so I used some 1000uf Nichicons, same with the input caps they were increased to 1.0uf WIMA's I used gold plated IC sockets instead of the cheap ones supplied
 

 

 

 

 

 
The sound is very good for something this simple and its running off batteries!!!
 
The bass is excellent partly due to the extra capacitance
 
Please understand this has been made purely for fun and the new owner is only paying for parts and postage, (no labour or profit)
sometimes its fun just to make something you haven't done before :)
 
will not be selling these
 
just sharing
 
cheers
