dbx 160SL PSU transformer

[kvintus]

Hi all!

I am looking for information on the mains transformer for a dbx 160SL (the blue one). It's a custom made thing with a dbx part number on it (26-0247-A1).
It looks as if there are 6 wires on the primary side and 10 wires on the secondary. I am most interested in what's what on the primary side.
I have tried contacting dbx through my local distributor but they couldn't help me much.

Does anyone have access to the schematics or the specifications for the transformer. Alternatively, could someone with a 160SL wired for 230V mains take a picture of how their 160SL is wired?

Thank you!

Anders

you have to use a step down converter if you have a unit that is designed for 110V

they are using a different power transformer for each voltage.

Wrong.

That's what I was told too at first. But when I discovered that there are actually two (center-tapped) windings i decided to e-mail the tech support in the US instead of the local distributor. And they replied with the info I needed. So the voltage conversion cost me a couple of centimeters of solder and 15 minutes of my time and now I have a fully working 160SL on 230 volts.

Hi
Do you have the wiring modification?
I have a 160SL in 110V...

Best

Wow. That was a long time ago. I have unfortunately lost the documentation on this thing but I still have the unit. If you give me a couple of days I will try to find the time to open it up and take some pictures and see if I can help.

Hi my friend
It's OK, I found it...
115V Orange + Grey / blue + White
230V Grey / Blue (Orange + White)

Cut orange and white wires to the main IEC and power switch. solder it together!

Best regards

Great!

Thanks for the info and the illustrated pics. I'll try that.

Hi I have a similar unit and curious whether mine is already converted to run off the 220V. Could someone please measure the resistance of the power terminals. Obviously, if the unit is set up to run at 120V, the resistance would be different than in the one accepting 220V.

Hi
I did this exact hack on a 1066 last week. If you disconnect the output from the psu , and test between the three wires you get 23v and 47v

Hi
It's the same with the 1066 and the 1046 except the wires are red and white that you need to cut and then join. On the 1066 the output is 47v leg to leg, 23.5 to ground. You can disconnect the output from the motherboard to test and prove the output is correct when you have made the hack.

How about the resistance of the input of the PSU?
