Default good job highand

good job highand this amp seems good when power is not important but the quality and the cost to own environmental speakers or small
only one question which component is SD
I will try to make this amplifier

soon will expose an amplifier with almost perfect driver
dt adjustable 0.4 ns to 1us
4 amp output + Input to output isolation for low noise need not shift lever
750v works more
8MHz operation until
seems like a dream for Class D amplifiers
greetings and good wishes to all
