This Data sheet. is about the 274A and 274B, which only difference is the tube base. These tubes are a full wave rectifiers of a special kind, and electrically equivalent to  the original  Western Electric historical tubes. Our tubes feature a series connected filament for both diodes together. The series connection  makes the middle of the filaments to be virtually grounded, when  using a filament supply winding with a center tap. This tube is can supply 140mA with a normal C-L-C filter.   The 274A and 274B are designed specially for Audio purposes, and is optimized for use with a small size first capacitor. With this tube, you will have only normal rectification current  flowing in the rectifier circuit, and no heavy current spikes.  This will result in less hum radiation into of the preamplifier, an improved sound compared to low impedance rectifier tubes for industry applications,  or solid state rectifiers.  Also the 274 is specially suited for applications with relatively high DC voltage. The new ceramic sockets we use, are a good help for this, since these give no leakage, and do not age under high voltage.
