Questions about tubes and gear that glows. FAQ

RE: RFT 6V6

These tubes are not fake. They all come in original boxes and have the same date code. These tubes are absolute NOS and have never been used. I have several tubes from RFT, 6SN7, 6SL7. some have the yellow and some white silk screen printing, same plate construction. @ Nunki; get your fact´s strait before yelling fake.

RTF used white silkscreen printing on tubes produced 1951-1953. From the year 1954 they used yellow silkscreen printing. Also, The real tell tail that these are in fact real RFT tubes is the ceramic mica.

RFT Mühlhausen even made tubes for Telefunken, Ultron, ITT, Calvert, National, Valvo, AEG and several other brands.
