diyAudio Power Supply Circuit Board v3 illustrated build guide

[Cooler King]

Just received my Toroidy transformer. I am a compete newbie here. I've asked a friend, but I'd like to confirm with you guys please. As you can see, secondaries are Red-Red, Brown-Brown.
So does red-red go to one bridge rectifier and brown-brown to the other rectifier?
Also, as this is 230v, UK voltage. Do I have one CL-60 on the live-neutral connector and x1 cap across the two white transformer inputs? I know this should be obvious, but want to double/triple check.
Thanks all for your much appreciated help!

 

[avitkauskas]

Yes, you are right about red-red and brown-brown.
Capacitor goes between the live and neutral. C60 goes on the live wire from the switch to the transformer. Perhaps pictures will help.

 

[Cooler King]

That's brilliant, thank you very much! I always thought the safety capacitor went on the transformer side.. And the CL-60 on the switch side. But I'll follow your pictures, thanks again!

 

[avitkauskas]

To be sure, notice that CL-60 does not go across the live and neutral (as capacitor does), it goes on the live wire.

 

[Cooler King]

Got it! Thank you so much..

The safety capacitor should be placed right after the iec, the masters said (not too long ago). I put it right at the IEC‘s connector-blades...

 

[Cooler King]

Ok, thank you.. I'll see if I can fit it there, although I've got this far at the moment..
Does it look ok? First time I've attempted to build a amp after 35 years in the hobby!

Looks fantastic!! Great job.

 

[Cooler King]

Thank you, appreciate that buddy

Does anyone know the CX, CS, and RS values when using an Antek AS-3218 transformer? Would greatly appreciate this info.

Thanks

It's on about page 5 of the quasimodo results thread, Off the top of my head, I think it says 10-12 ohm resistor with .01/.15 mf.

 

[Leicaphile27]

Just to be clear, CS=.01mf and CX=.15mf?

 

[mlwebb]

No.
See the pdf in the first post
Cs should be larger than Cx

 

[Leicaphile27]

Thanks for the clarification...Much appreciated!

If Building an Aleph J with a 400va 18v transformer and 15Kuf 63v caps, can I use the Mur3020 diodes in the bridge section of the DiyAudio universal power supply?
I ask because I have them and heatsinks on hand.
Also would like to find values for the snubber resistor and cap RS1 and CS1 ?

 

[6L6]

Yes.

Look at the “Quasimodo results thread” for your transformer’s values.

 

[rtate]

Thanks 6L6 !
I have studied the Quasimodo results and while the cap values are fairly consistent, the RS value is a very wide range anywhere from 8-19ohm !
I was wondering if over time the group had settled on a value ?

 

[6L6]

The cap values are consistent as they stay the same, only the resistor is adjusted to the specific model transformer.

 

[rtate]

Agreed , but for the Antek AN4218(which I have ) there are a few different resistor values throughout the thread

 

[rtate]

when hooking up the power supply for initial testing with a dual secondary transformer
using the discrete diode section of the board, does one secondary go to AC1A and AC1B and the other go to AC2A and AC2B ?
