Dr.Tube is dealer of the excellent Mercury Magnetics transformers and chokes. Dr.Tube is also part of the Mercury Magnetics Service & Support Network! This greatly improves the ability of Dr.Tube to help you choose the right transformer(s) and/or choke for your specific wishes and amp(s).
Why Mercury Magnetics?
Transformers are expensive parts. That's why (almost) all manufacturers of guitar amps will first cut costs on these parts. The output transformer is the link between the power tubes and the speaker(s), so the output transformer has a very major impact on the tone of a tube guitar amp. In practice we have seen (and especially heard) that the output transformer very often is by far the weakest link. Mercury Magnetics manufactures very good sounding output transformers, power transformers and chokes specifically for tube guitar (and bass) amps.
Mercury Magnetics manufactures transformers according to the old and classical recipies, the Tone Clone series, and also manufactures transformers according to newer and more modern insights, the Axiom and the American Pro Series. Accurate clones of the RS (Radio Spares) transformers, for the AC30's and JTM45's are available as are several Partridge clones.
By replacing the mediocre/bad sounding output transformer and choke by one of the Mercury Magnetics transformers and chokes (especially for amps after the 1970's) will dramatically improve the tone of your amp. How the tone improves is always difficult to describe in words but the following list summarizes this nicely:
Which transformer do I need?
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.
