One moment away from the baby genesis!... parts collected, prepared for soldering 5 power amplifier modules but sometimes it seems to be bewitched: no 18V Z diodes on stock 😱
Happy soldering.🙂
What kind of solder wire are you using?

Mostly I'm using "alpha NO CLEAN Fluitin 1532, 0.75mm".
(funny: There is an expiry date printed with 2016.06.03 - but still doesn't "smell" and is good to solder - maybe some RoHS expiry date?)
I have RoHS solder wire too but to solder using the pb-free solder wire is painful ...

I always recall those gleaming glossy soldering pads when Philips made soldering wires was in the market.

Always i go fast up to final test.😉... tired. not much progress, a small step forward ...
Then all my projects stops because of cost😡

Final design sa2013
Hi astx,
Need your help with the power amp sa2013
This project and discussion is quite long and a lot of corrections.
Can you help and show me where is the final design and schematic. Did you build this project to your satisfaction?
I have seen that you changed the main Vcc supply from +/-70 vdc to +/- 63 vdc and a lot others small changes.
I am very curios to know if is working properly.
Your help and answers are very much appreciated.
Best regards,
Williams

Dear Williams,
have a look at the index in first post of this thread.
SA2013 has been renamed to SA2014. => see index position "A) SA2014 (200W@8R, 400W@4R"
Rail voltages are +/- 72V when listening low power and +/-62V when providing continuous full power 400W@4R.
You need to use minimum 80V capacitors in your power supply when using 2x50V transformers. For a single channel a 600VA transformer is recommended.
The amplifier is running perfect nearly every day. No known problems.
BR, Toni
P.S.: Steve aka "SGK" has build it also successfully - see links in index.
Yes this is a case from modu!Wow - looks like you've got a case from Modu! 🙂
Have Fun, Toni



Unpacking procedur.
The first time that i be able to have such a thing!
I hope that my SA 2015 will be very happy in this house soon.
