700W AMPLİFİER!

[Sierra]

Another 700W amplifier!!


Power Supply is +-80VDC


Enjoy!


Some pictures and full files in ZIP format!

Friend, it looks like a monster very good project but you can add relay circuit. because you can get huge start sounds on +-80v BUT it have very symetric design i like it !

There are 3 trannies with no component name

 

[engel]

can you please share component overlay and bottom pcb
thanks

 

[khalsa]

can you send files in pdf

700w on = R load? 2R,4R,8R=Wrms?

 

[JAKUB_G]

700w on = R load? 2R,4R,8R=Wrms?

Output power: 680W/2R, 450W/4R, 260W/8R Measured on 550VA transformer with 2x54V AC non-loaded
Everything you can find below:-

hi Sierra,

FYI, the file was corrupt ?

[irvynejay]

i will try to make this one

hello buddy,
how about the four bias diode,mounted on heatsink

Yes, at first I only forgot to attach.

See last post from Jakub_G, All files now complete


Thank you

That sounds good, Please would you tel us the specifications of this amplifier?

Output of amplifier with frequency response? max power


Thanks

hi Sierra,

How is it sounds impression compare to super leach amp? can you share us video on your test?
Thanks and more power.

Thank you

Ok, i've downloaded the file.

thank's alot.

hello buddy,
how about the four bias diode,mounted on heatsink

These diodes are substituted by one NPN transistor as you can see in schematic diagram

That sounds good, Please would you tel us the specifications of this amplifier?

Output of amplifier with frequency response? max power


Thanks

freq response: 10 - 180 000Hz/-3dB
Max power 700W/2Ohm
Slew rate: 35V/us
TDH+N: <0,07%
IMD: <0,04%

Superamp is more dynamic in basses, but it has a disadvantage-the power dissipation on the power transistors is higher, than in the case of classic parallel output stage.

thank you,
absolutely that was one of the transistor mounted on heat sink,one way of eliminating bias diode as of the original designer prof. Leach amp sec. stage
