Mercury Magnetics manufactures literally hundreds of different (drop-in) replacement transformers for even more different amps. It is unfeasible to have all these transformers and chokes in stock. Dr.Tube has a selection of some common and popular types in stock. For other amps the transformers need to be ordered. To keep (shipping) costs down the Mercury Magnetics orders will combined as much as possible. This means that the lead time can be a couple of weeks. If you are in a hurry, single transformers can be ordered, but the higher shipping costs will be charged. These extra shipping costs will be very dependant on the transformer and its weight and the continually fluctuating dollar-euro exchange rate.

If you have any questions, feel free to ask them. We like to help you!
