The Gold version has a ceramic socket with gold pins.  Datasheet , Curves Detail1 , Detail2, Detail3 Day-glow , Nightview 1 , Nightview2	300B replacement. BUT..... Important: For 300B/n  =MESH tubes Recommended use value: 22Watt for  best lifetime. More mportant:  For 300B/n  =MESH tubes Maximum 28 Watt.
2A3/n This is a mesh Plate 2A3. Construction is like old RCA tube. 2A3/n	Fullsize image , Datasheet1 , Datasheet2 detail1 ,	Direct replacement for any 2A3.
274A 274A/n 274B 274B/n	274A,  274A/n, 274B, 274B/n These are an quivalent to Western Electric 274A/274B, using the nice big glass of the WE300B.  274A and 274B are the same tube, apart from the socket which is different.  274A used an UX4 socket, 274B uses an octal socket.  274A/n, 274B/n are a mesh version. Important Note:  This tube is a special audio rectifier, with a higher plate resistance than industry rectifiers, such as GZ34 or 5U4G.  The advantage if this is a soft "on" characteristic while charging the first capacitor.  This is the principle of how to use this tube: The 274 is made to run on a small value first capacitor, and the value is limited at 4uF maximum, by the official WE datasheet. This will result in lower hum, and much improved sound quality. The AC rejection will come mainly from the choke, which must have a high value (15...20H) and ideally symmetrically constructed with two coils for best noise rejection. (Like Lundahl 1673/20) The second capacitor is used for fine ripple rejection, and overrating of this capacitors is possible, as much as you want.  Fullsize image , Datasheet , Curves 274A-Socket , 274B-Socket Mesh plate , Getters	Max 140mA Rectifier  for HiFi  Low hum type with soft characteristic.
274B/n+	Click Image, and  see how impressive size this  tube is.  This is no trick image! Also the glass is a  most beautifull,  hand blown balloon.  Very smooth surface. Buy it, and you will experience this wonderfull tube.  Most recommended product. The night view of the tube is truly magnificent, because of the big size  filament This is a large size 274.  has twice the filamant current, and lower voltage loss over the tube.  Customers reported up to 25 Volts more output voltage with the same transformer.   Fullsize image , Datasheet Side1 , Getter , Side2 , Day-Glow	Max 250mA  Rectifier  for HiFi.  Filament rating:  5V / 4A
