Features
- In 2011, we have included inside the tube glass a special element to stabilize the heater voltage. See also the pictures on the right. (or here) These elements at higher current, will increase their resistance, and help protect the heater against accidental over voltage.
- Slow Start ( 2…7 seconds)
- Filaments are series connected, for best symmetry of the two diodes inside.
- Extra large getters.
- Each tube is numbered, inside the bulb with a metal Tag.
- Extra large getters, flashing the complete tube bottom.
- These tubes are shipped in a high quality box.
- Tube printing with real gold (metal), red color is burned into the glass.
- In 2011, we have started to ship 5U4G-mesh with the new ceramic socket, with five pins. From Yamamoto, the Octal 8/5p Teflon socket is recommended. This is an octal socket, but has five pin holes only. It is specially used for this rectifier. When working with Octal sockets, you will find the Yamamoto an amazing top class product. For this rectifier you can take the special octal version with five holes only. Like this you can never put in a non-rectifier tube by mistake. You can also use normal octal sockets of course.

This data sheet applies for the 5Z3-Mesh and 5U4G-Mesh, which are electrically identical, apart from the sockets. 5U4G-Mesh uses as Octal Socket socket, of which only five pins are used (and one of those is electrically not connected). 5Z3-Mesh uses a four Pin UX4 socket.
These are direct replacements for the historical 5U4G or 5Z3. They can not replace 5U4GA or 5U4GB which are different tubes. See Note 4
Note that the Emission Labs® tube is somewhat larger size than the historical tubes. Check below at mechanical data, for details. Like most NOS rectifiers, also the EML rectifiers are Slow-Start tubes, protecting the power supply and the whole amplifier to some degree. The delay time for first function is 2 seconds, and the delay for full current is 7 seconds.
