cool!

but some parts are VERY HARD to come by... almost impossible to get

Bender.ru · 14th April 2008, 03:24 PM

Hi RX5!

whta parts do you mean? i think that onle one part hard to find is doubled output fets, maybe driver.

luka · 14th April 2008, 03:28 PM

Hi

Maybe driver and AD other then that... Very nice how you made some sort of report, 10/10

RX5 · 14th April 2008, 03:29 PM

Bender,

Im in the Philippines... much URBAN than other, and yeah, the real hard && impossible to get are the Dual MOSFETS, the mosfet driver and the "AD" input....

The mosfets could probably be subd with single N-Ch mosfets...

anyways, nice that you had that thing going...

how about adding a protection circuitry to it?? or how about converting the driver chip to a discrete one?

Cheers!

hi Luka, thanks for reply.

i put ad825 at input, because i have ones for free

you can replace it by tl071, ne5531 or other soic8 single opamp without any perfomance derating

Most of them are pin-to-pin compatible.
It's easy to trace pcb for usual to-220 case fet, if you want, i can do it.

ps: what kind of protection do you mean, OVP, UVP, OCP, OTP? my project is only simple sample of DIY amp not for commercial use.
