For those considering any of these, I ordered from Boris before and the transformers were exactly to spec and very nicely done. Great value.  :thumb:

Lower cost due to the stronger US Dollar!  :thumb:

Last order was priced at approximately
Euro = 1.6 USD

This time the exchange rate is better than
Euro = 1.4 USD

Savings of more than 10%.

We are passing this benefit to our customers worldwide (even our EU customers will see a lower price).

Oh Charles, you are way too kind!

It makes me very sad that Trafomatic decided to stop making custom transformers for DIY market. They got very busy, costs went up and they could not allocate resources to support high mix, low volume production.
