Hi Brizco,

No offence, but you really, really need to do some homework yourself.

Read the appropiate metas. Do some searches. Read some data sheets.

And if you in that process come by any questions, ask them here.

hello jakob!

im not lazy :cry: i searched for about 2 bours and i found the original telefunken modul schematics and some others, so i have schmatics for a 24v psu.

probably i asked wrong. i search for a schematic that other people use with their siemens w295 or other compareable gear and its well tested. and it should be simple, not like the telefunken psu.

but if this post ist disturbing, delete it. :wink:

bye

Hi Briz,

No problem, really! :grin:

It's just that we want to encourage people to try for themself..

Take a look here:

for all german speakers like me...

thanks for all the "help"

bye

brizko: you have to built it as unregulated single ended , because german stuff have the regulator onboard, but regulated one works just the same.
 
Briz,

Depending on your current draw, you may want a larger first reservoir capacitor. The 1000uF is fine up to some 200mA or so - if you use more current, add more capacity.

Also, the second 100uF capacitor, is a bit large - the regulation in the 78XX's don't really like to look into too large a capacitor at their output. A 1-10uF would probably make the circuit more stable...

thanks a lot, i will try it. made it with the 100uf and worked not bad.

by the way: i recieved today an email from a guy that sells ssl clones...
ill forward it to you.

bye

Thanks Jakob, that's actually something I always wondered about. Is it the same with TL317 or TL783 regulators?

Yes, I believe it is..

Though on the G9 HT psu, I have a second, large, reservoir capacitor after the '783. But this is AFTER a 470R resistor - so it shouldn't influence regulation..
