Siemens RFT EL34 / 6CA7


Some of the last production of the German Siemens RFT EL34 / 6CA7. They are compatible with the American designation 6CA7 so they are drop in replacements. Very nice tone and well built. It is the slim profile EL34 with dimple top and halo getter. They were sold for use in OEM and are unlabeled.

    Fantastic tubes. Sonically equivilant to my SED Winged C tubes which are some of the best tubes I have ever heard. Very pleased with the transaction. Will continue to do business with Craig and company!!

    Great service. Got the tubes in a few days. Packed extremely well. Sounds awesome in my RedPlate Magica. Huge upgrade from the JJs that were there (after necessary re-bias).

    These tubes are fantastic, much better than Mullards and have dramatically improved the character of the RedPlate Magica.
