Siemens / Haufe transformers  
   

* From the parts with askerisk I have singles. I offer them for trade or will buy yours!

MORE INPUT TRANSFORMERS FROM OTHER BRANDS HERE!

Please ask me if you need transformers for your MC cartridge!

 
   

All Siemens / Haufe transformers are mu metal shielded. They all have the yellow or orange tape where their type number is indicated.
