We inaugurate this new section with an extremely interesting tube. Produced by the Hungarian Tunsgram at the beginning of the 70's, it was classified by the manufacturer as "industrial grade" you can see an internal plaque on one of the getter holders to indicate this special selection, which included: optimal balance between the sections, low noise, guaranteed long duration.


They were produced under the name Tunsgram and on behalf of third parties in a limited quantity, estimated between 5000 and 10000 specimens


It sounds very balanced with the right definition on the highs and a very hot and natural medium range. A sort of midway between Mullard and Telefunken


At Tunsgram brand you can find them online not less than $ 75-85 a


We have about thirty of them, if ordered in pairs or quartets will obviously be selected and matched.
