"Micro Bamboo Project" : 3E Audio 260-2-29A Stereo amplifier + Micro-Audio PSU

[brunes]

Ok, audiophonics delivery is here, now the questions start!
2 power supplies from one IEC, is it best just to solder 2 cables to the IEC tab (twist together to make 1) - 2 cables into a spade connector doesn't seem cool.
Any other solution that I'm missing?

Best way for dual mono (I shared it in previous thread). To get a clean cables management

But how are you splitting 1 IEC tab input into 2 ? are you splicing the cables ?

As you van see on graph splitting is done from PSU1 AC inputs ))) you double the cables from here easy-)

"Bamboo Project" : Dual Mono 3E Audio 480-1-29A Amplifier

Hi amigos, Following the ASR review of the 3E Audio 480-1-29A Module, I decided to roll up my sleeves and show you that with a little elbow grease, you can create a very beautiful amplifier based on these nice 3E Audio modules. I called this project, "Bamboo"> the pictures will speak for...

That looks like 2 cables into a spade connector... that might work if I use standard Spade for IEC and bigger spades to join the 2 cables.

Ah or there are even these

I shared you the best easy practise... Why do make it difficult ? Less is more....

My cables are too fat to join at the jst connector and don't fit in a single faston...
I don't see how to join the cables

Show pictures and a diagram of what you want to do ?

I'm just giving you some DIY advice: I model all my projects on an A3 or A4 sheet before making them. Ditto regarding the implementation of wiring and soldering etc. I always carry out continuity tests and all this allows you to have an impeccable projection afterwards)

He is just looking for actual practical advice on how to connect the cables. Not theory and unclear photos.

@brunes any of the ways you have listed above will work great.
PE makes larger gold plated spade and fastons that you could get 2 cables into one, as well.

I agree and it is exactly what I did previously by sharing a super simple diagram to avoid any mess with all those cables --))

Tthese are very solid

WAGO 221-413 Insulated Terminal lever-operated 3-conductor 4mm²

This Wago 221-413 domino is a lever-operated compact connector ideal for conductors with cross-sections up to 4mm². It allows quick and easy connections thanks to a lever system.

Thanks for the support!
I get the idea, I don't get the logistics of it I have 2 fat cables that I can't join at the IEC end with a FastOn connection or the SMPS/JST end.
So somehow I need to join 1 IEC tab to 2 cables.

The wago look good, will go with those! Thanks.

Nice show us your final result when it is all done )

Wow yesterday there were 25 boards in stock at 3e. Today zero!

 

[brunes]

Can I ask about grounding
1x IEC Ground to case.
Should the x2 SMPS then ground to a separate grounding point?
XLR pin1 to chasis (ground tab on xlr)
(3e audio boards no specific grounding)

This module was a victim of its own success lol

To help, Hypex recommendations :
I would ground both PSUs to same point.
