You might want to check with Hart at Audio Advancements. I'm pretty sure that he was once the importer of Klimo is the U.S.
Looking for Klimo distributor or contact information
Does anyone know if Klimo is still in business, if they have an US or North American distributor, or contact information. I could find nothing on their website. I am looking for someone who might be able to repair their pre-amp and power amp (all tube stuff).
