Power Amplifier and Power Supply Full PWM

I am interested also...

hien.t.nguyen any updates with the first construction of the L25De and your SMPS?

Curious if you will build one yourself for testing? Also interested in pricing for single units. Your pricing structure was for 20+ units being ordered. You never gave a price for the SMPS only linear. Will you sell these through ebay? or direct? How would I pay you?

Big amp has one mistake on the schematic is driver not use 2N5551/5401,must use ZXTNP25100/ZXTP25100

Holy smokes! You are busy! That amp is a Class D monster! What are you going to use that for?

I can wait for your L25DE. Your L25DE looks really good. I would love to see results from a unit operating prior to my purchase

Very nice amplifier.
Did you build it ? If so, what was the performance ?
