Default ±50V SMPS for Quasar Amps (& others)

I learned from Alexmm about a SMPS designed for the QUASAR and decided to open this thread since other projects may benefit from it.

The schematics can be downloaded HERE.

The first group buy is now closed, but the second one is still open HERE.
If you are interested you can register in English.

I understand from Tibi that these boards should cost around 7 Euros each plus shipping.

Please let me know if you are interested so we can consider the possibility of having boards for all US buyers sent to a single address for redistribution ($aving $hipping).

At this point this is all I know about it. Probably Tibi can help out answering questions.

Cheers!

The photos don't match the schematic. (TR2/TR3 interchanged, diodes marked D104-D107 in the schematic and D7-D9 on the board).

Is the board in the photos a later revision ?

Guys

As mentioned above, I wrote all I know about this project.
I will contact Tibi about this post and ask him to help.

Yes, it would be nice to hear from people that already assembled and tested this power supply. Since the first group buy has ended, there is probably a few people out there that can provide feedback.

Thanks!

Alexmm posted a photo HERE so perhaps we should have some feedback from him in the near future.

We are going to share all info's but not the gerbers.
Behind PCB layout is lot of work and we prefer to benefit from this at some point in time.

Shipping will not be an issue if someone will redistribute the board within US.

Regards,
Tibi
