Emission Labs 5U4G Mesh / 5Z3 Mesh Rør
Pris er per stk.
Description:
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.
Guarantee program for first owner.
At EML we have the normal guarantee. In addition to that, the first owner can register the tube within 4 weeks after receival, at the Emission Labs® website, to participate in the 5 years guarantee program.
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.
Two extra large getters.
Each tube is numbered, inside the bulb with a metal Tag.
Two 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.
