Under the impact of streaming audio, Vicol Audio has been supporting for so many years, and finally closed...

Thank you, Clayton !

Vicol Audio was a hobby business. It never intended to compete with anything.
But, hey ! I'm still here to offer support, learn and develop new things for this great community.

Regards,
Tibi

Please note that output +8V must be connected with Sense as close as possible to Shiga MKII connector.

Please take care that Zeno do not work without sense wire connected.
Sense wire must be connected at the load, as is clearly reflected in attached pictures.

This is to recall that Zeno is NOT a direct replacement power supply for Shiga MKII.
You need to take care on how to connect Zeno as per above drawings.

If you use Zeno with original Shiga MKII transformer, please use only one secondary. This way you have ~10Vac at Zeno input and power dissipated by regulator will be in normal limits.
If you use Zeno with Saligny, than you may use a trafo that deliver between 7Vac and 10Vac at 2A.

Regards,
Tibi

Hi Tibi

Is there a manual for Zeno?
I am looking to make 26v - this is greater than the jumpers allow; I'm guess extra parts are needed?

Thanks
Clayton

Hi Clayton,

For 26V output you need to use R11 and R12 and no jumpers.
R12 = 10K
R11 = 174K

Please note that total power dissipated across regulator must be under 5W. For this use a transformer that have in secondary min 20Vac and max 22Vac.

Regards,
Tibi

Thanks Tibi

Just to check that you refer to the voltage output (Vac) not the wattage (VA) that should be within those lower and upper limits? Sometimes I find transformer labelling confusing between the two.

I will check what I have before I proceed - I don't think I have anything at home between those values but might have a 20Vac there? Plan to try Zeno with TDA1541A Distinction V3 board.
