Hi there.

Well, finally another scandinavian guy. I'm from sweden. I've only come across 
3 people here in the north. You, me and Kristian in Finland.
Sorry to hear you have problem with the driver for your TC.

But if you search around you will surely find some used or discarded
neontransformers. I did. 

So tell me more. I'm interested.
