Default We need huge heatsinks to use Super A, the transformers also is bigger

rectifiers must be bigger, filters must be bigger (15.000 plus 15.000uf) to a single channel.... it is almost a new amplifier...so, people that has made the Dx Blame ST and want to use the Super A features, will be forced to replace some parts and to use forced air cooling.

Default It is almost perfect Juan...it is time to finish to release it

put something to separate Layout Designer - Juan Vargas and reduce your "frog" or increase my "Dx" in order to make them same size...and anything more to comment.

But we have (you and me) to give a tripple check in all connections to see if anything was missed or shorted, or having tracks almost touching each other (avoiding this way, solder shorts and capacitance trouble)

Not layout designer Juan Vargas, put Layout designer: Juan Vargas .... or Layout designer - Juan Vargas

Congratulations Juan...you have learned from the begining...made it from the scratch, and even this way you have made it so good as a professional.

But we took two or three weeks..... Alex mm do that in 50 minutes or less.... the guy is a layout machine!

regards,

Carlos
