What are you planning to do with this?

 

[hn702906]

I tried to replace the original PCB because the original PCB was deformed due to high heat.

 

[hn702906]

At the same time I also launched a replica kit of A504

That would be a lot of work to replicate the PCBs, well done.
Please show us more!

Sorry, I may be stupid, but there are a lot of reference A504 amps, which one are you talking about ?

 

[hn702906]

Luxkit A504

I think it is the same as the Z504 kit version.

 

[hn702906]

yes .
A504 and Z504 are same.

I worship these old Japanese designs. Way ahead of the game.

New PCB arrived，Let's do it!!!

Looks excellent quality, well done. Will you repopulate with the original components?
I have rebuilt 2 x Z504, one with original semiconductors and the other with modern equivalents (apart from the K170s)

 

[hn702906]

I plan to make two different A504,
One is the original components and the other is the new part.

then see what's difference🙂

What software can make those beautiful organic looking tracks? Converted from image pergaps?

I was thinking the same; those lovely curvy tracks just like the originals. Excellent work.
