This is a set of very early Marinair transformers dating from ca 1970-1972. The two input transformers are the green can with the yellow label which are the most sought after version of the Marinairs. The set consist of the following:Marinair 10468 Microphone input transformerMarinair 31267 Line input transformerMarinair LO1166 Line output transformerThese are perfect to use as an upgrade for your BAE, AMS-Neve or Heritge input modules where they are huge upgrade and will turn those modules into something that is extremely close to sny vintage Neve inout module. Or you can of course use them for a DIY Neve build as well. There is a huge difference between these originals and the new version from Carnhill and these old ones simply sounds alot better to my ears. I have done extensive tests between different versions of the Carnhills and different versions of the vintage Marinairs and St Ives and in my opinion these early green can with yellow label input transformers are the best. I have a few of these sets available so please pm me with your needs. Worldwide tracked shipping included in the Buy it now price.
