Is it that model? http://www.antekinc.com/pdf/AN-0515.pdf

If yes, then you go red/red, black/black to live/neutral, inner blue/green to dcb1 connector's center, outer green to one outer connector's point, outer blue to the other outer connector's point. 3rd centre IEC prong you drive it to chassis. You switch black/black or red/red if with a single pole mains switch.

Use the bulb tester as already advised.
Power up the transformer alone through the bulb tester.
If OK add the DCB1 to the transformer.
Power up through the bulb tester.
If OK then put it all in a case.
Power up via the bulb tester.

When you have completed ALL modifications do a final power up via the bulb tester.
Finally put the bulb tester on the shelf for the next project.

Listen to your DCB1 & system.

Some questions:

- Can you only get 2 poles / 6 position rotary switches? I don't really need 6 inputs, probably more like 4. Is there a 2 pole / 4 position rotary out there?

- In the BOM pdf document in the DIY store it's mentioned that the 4700uF caps should be with 7.5mm, but in the same pdf it's mentioned they should be with 7mm. 7.5mm is the correct value, right?

- Is this a good choice for 100uF cap?: 100uF 35V Elna Silmic II Electrolytic Capacitor

- Is this a good choice for 4700uF cap?: 4700uF 35V Nichicon FW type, UFW1V472MHD

Here is my Mezmerize BOM in progress. Maybe it can be useful to others too: https://docs.google.com/spreadsheet/...HkyMDZDM2txdWc

Thanks.

the 12w rotaries are generally available as:
1p 12w
2p 6w
3p 4w

I can't recall seeing 4p 3w nor 6p 2w

Some are fitted with an adjustable stop. You can limit a 2p to 6w or 5w or 4w etc.
Check each manufacturer's datasheet.

Arh, now that's clever. I didn't realize that.

I'll start searching. Thanks for that.

Thanx Salas/AndrewT, for getting back to me so quickly.

Very much appreciated as usual.

I think I now have a better understanding and I have in fact wired correctly, to connect to the 3 pole power switch.

Salas, you have it correct, I am using the AN-0515 transformer.

AndrewT, makes sense to use a light bulb tester before going live, which I plan to do.

Again, such a simple thing, yet confusing if you donít do this on a regular basis.

Thanx again, Fred in Canada

You are welcome. A video about the bulb tester from an antique radio guy.

Hi Fred:

Your initial description of your switch wiring sounds very wrong. Your "3 pole" power switch must be a single pole double throw switch. It connects the center contact (think of it as the "output" contact) to one of the other two, depending on the position of the switch. So it can only be used to switch one leg of the AC circuit, either the live or the neutral. Connect one side of the transformer primary windings (the 2 reds or the 2 blacks) to the center contact, and the hot AC from the IEC socket to one of the outside terminals. Leave the other side unconnected (but insulate it for safety). Connect the other side of the transformer secondary directly to the other leg from the IEC.

Then disconnect everything and throw the switch away, and replace it with a double-pole switch! With a double-pole switch you will interrupt both legs of the AC and so can never be caught out by a miswired AC receptacle.

Here is a picture of my double pole single throw switch:

power_switch.jpg

The terminals on the top are to the transformer, the two black leads on the left and the two red leads on the right. The terminals on the bottom connect to the IEC socket, neutral on one side and hot on the other.

Either way, make sure there is a fuse in series with the transformer primary, 0.5A should be plenty.

- Would it be okay if I use the Antek AS-4434 where the 2x34V supplies a classdaudio Heavy Duty DC power supply and the 2x15V supplies the Mezmerize board?

- The BOM mentions I should use a 2x12V supply, but can I use a 2x15V without any modification or change of parts?

Yes, many use 2X15V for the DCB1.
