Got som problem with connecting this to the amp because i see that the colorcoding of the wires on the new transformer doesn't seem to be the same s on the old one's...
Could this transformer possibly an 120v version, and if so... Is it possible for me to convert it into an 240v? Andreas

Where did you get it from ?
If you got it from a shop, they must have the wiring color scheme... Isn't there any label on it ?? Maybe a photo here can help identify the colors

I got it from Troide Electronics in the U.S.
The thing is that, after i had got the package (it's containing maintransformer, 2 output transformers and a choke) i found out that the firm sold a 240v transformer which gave me a little scare. That there might be a chance that so is. The scheme which i downloaded from TE shows this 117v, which confirms my suspicon. I can put in pictures and schemes (dynaco and transformer) in 30 mins...

Hi,
If it has a purple and purple/white lead then it is the export version. This version can be wired for a 117v or 240v primary but you need to join the primary leads together in different ways to achieve this. I used to have a wiring diagram for this transformer and will continue to look. In the meantime, email Matt at Triode, he will send you a wiring diagram - they are very good over there. Cheers, Rob |

Hi,
So it looks like you have the export version. I have used it myself and it seems to be a fine transformer. Good luck, hope that it works out OK. Cheers, Rob |

Thnx again, Rob..
But since there are no purple leads or any who look like purple except black i'm still a little lost, but i'm going to ask Matt at TE and see if they got any "schematics for dummies" to e-mail me
