Heres is very good sounding amp you will need to add 3 Pair Output devices for 80 V DC


for 200 W 1 pair like schemtic is ok, you will need to change 2 devices for 40 V DC @ 200 W

PCB Files available for TARGET not EAGLE

Nice but doesn't look like class D to me, so don't forget to add a hefty heatsink ... just sayin'

I know it's not exactly what you are looking for, but LJM's class D modules based on the reference design for the IRF2092 (look for L19D, L20D or L25D on here) are so cheap and simple, that I wonder if it's worth starting from scratch

Hy everyone,
I have the same problem finding a schematic for an amplifier, I have a Monacor SP-385G speaker, as I understand it has 175WRMS@8ohm load, so a 200W amp will be enough, I also have some parts that may be used in power amps, 4 x 2SD718, 4 x 2SB688, 4 x TIP35C, 4 x TIP36C.
Any advice would be helpful, thank you!
