Does anyone else get a wrong link to tradetracker.com ? when clicking the conrad link ?
Anyway the trafo is the right one, just go for that one and just buy 2 of them and replace the GT and ST you wont regret it.

Yeah, I get the tradetracker as well. Maybe it is a good idea to replace my transformers as well Smile

Try copy & pasting this in your browser:

conrad.nl/nl/universele-nettransformatoren-12-0-12-v-1-5-a-36-va-elma-tt-516007.html

Looks about right, voltage- & power-wise. Do check physical size (datasheet!) to make sure it will fit. If needed, mounting brackets can be removed to install transformer on its side.

Note that the old transformer probably isn't damaged much. But most transformers include a thermal fuse that's packed in an impossible-to-reach place inside the windings. When overheating, usually that fuse blows before real damage is done or something catches fire... Shocked!

Just go to Conrad's site and search for "516007". I found it there.

Bummer... Hard to say what actually burned down. What does visual inspection reveal? Any deformed/darkened/melted parts? Burning smell from any components? If I remember correctly some transformers had a protection against overheating. When getting too hot they simply stopped working.

Erik Luppes has a guideline for changing the transformers in Turbo R ST. But I am not sure whether this will work for GT version. Here's the link anyway:

In the worst case some components on the board could have been overloaded and stopped working. If those belong to the AC/DC converter circuit, you are lucky. If one of those big chips is broken, I am afraid your machine is a brick...

I can confirm, that it also works on a GT B-)

I am going to try to replace it. I have a few questions before I begin with this adventure:

1. The item 516007 on the Conrad site has 2 for the 220V and 4 pins for the 12V while on the instruction site of luppie there is a transformer used that has 3 pins on the transformer. So this item is a bit different. What should te pin layout be for the 4 pin variant?

2. I am wondering how to attach/fix the transformer to the case so it won't travel through the case when moving the Turbo R around. Any suggestions?

3. I think I prefer to use a 220V certified power cable instead of the original. The orginal cable has a square rubber that closes the gap and protects it from pulling. Any suggestions on how to lead the cable in to the Turbo best?

4. Any suggestions on which shrinkwrap item I need to order?

-> This transformer is the one to use, and i have orderd 2 of them and they have 3 terminals for 12-0-12 volt.
See the PDF of the trafo.(see also the only comment there is on the dutch conrad site with this trafo Smile

--> see picture, i used a piece of aluminum of 20 by 80 mm. fill up the gap of 4 mm with some rubber or somthing.

--> use this original cable protection, cut the original cable at both sides and use a 4 to 5 mm drill to open up the hole where the cable goes trough, use some soap or other lubricant to get the cable trough.
see second picture.

Thanks a lot. This helps. I got the transformers and they have indeed 3 people pins instead of 4. I also ordered 80x20mm aluminium plates but where to get heat resistant rubber that size for a reasonable price?

You mean to fill the gaps? I used a pice of rubber from a old bike tire.
A mantle pice of rubber wire canb be used to.

Thanks. I ordered some EPDM cel rubber with the right size which is heat resistent till 120 degrees and custom made aluminium 80x20. Waiting for it to arrive.

Today also some good news: I connected the new transformer to the wires and it works perfect. When I get the rubber and the aluminium I can close the case and enjoy my Turbo R again Smile
