Very Kind from you to call this nice work
In the reality it is a very bad construction, board etching was terrible, i have made so many shorts, so many mistakes, so many inverted transistors, so many errors that i just cannot believe the amplifier have played at the end.
But finally it worked fine... after several shorts discovered, missed lines, missed parts, missed holes, wrong way parts inserted.... uncle charlie is becoming very old (now a days 61 years old).
Soon i will receive lovely pcboards, from Juan Vargas.... these will be really pretty ones.
regards,
Carlos
