For sale ETI477 PCB's

[Leinster Lad]

Getting geared up to restore my old ETI Series 5000 power amp (which uses the ETI 477 boards )

Lots of learning from various forums with circuit modifications and updated components, so I thought "why not" !


I was not happy with the original boards, as some tracks lifted when I depopulated them and there was also some scorching around the BF469/470's

So, after a LOT of pain etc, I managed to copy the board design, created the Gerber file and had some (10) new boards made.


These new boards are not drilled as I will use the old board as a drill template, and I have some mods that I want to try that require new holes anyway.


So if anyone needs a new board or two, hit me up ! Pics attached.

Leinster,

How different are these to the original pcbs? What exactly are the improvements?

Thank you,
cheers,

Boards are an exact copy.
They are undrilled at this time.


Plenty of improvements and ideas in these forums.
