Hi,


Iam Looking for replacement/improvised amplifier boards for Denon POA 2400. Is there some one who makes replacement boards or modified boards with todays available components ?


Regards,
Suman

While the actual power amplifier circuit isn't bad the board has a lot of safety devices etc that would incur a lot of time and availability of parts to replace .

It gets a very good write up but looking at the schematic quite a few parts are marked as "critical use manufacturers recommended parts only" , if its faulty why not try and locate the fault ?

Suman take a note ,after some checks working POA2400,s sell for $350-$500 even a full rebuild will set you back near that figure and if you want somebody to do it for you you have to pay for his time .

Where are you located?
What is the problem?
Why not service or outright replace the unit?

I redesign this boards. There are not 100% perfect but the old one have traces lifting on hot transistors.
This amp deserve to be restored, great sound.

They break down a lot. I sold my boards and put in @ljm_ljm boards that fits the 70 volts from Denons psu. I think they were L25D, but Im not sure and not home now. Maybe LJM can advice you.
