EML 300B25

EML 300B25-Mesh

Released and ready to ship

Warning: This tube can not be used in a classical 300B amplifier. For testing with a tube tester, you need to use 2A3 settings

The EML 300B25 is a direct replacement for the 2A3 tube. Users of 2A3 tubes have a limited choice of tubes to use. There was only 2A3 and 2A3-Mesh. With the 300B25 we offer an alternative tube. The idea is to get a slightly different sound, and possible a small gain in output power for any amplifier.

Guarantee


The first owner can register the tube at the Emission Labs ®website, to participate in the 5 years guarantee program.

Some Background of this tube

It is interesting to see, electrical data of the 300B tube at the operating point of 2A3 is very similar, and apart from the heater voltage, a 300B could replace the 2A3. So we have put the heater of the 2A3 tube inside a 300B, to get a 300B tube with heater specifications of the 2A3. We have called this tube 300B25 ("25" stands for 2.5V heater)
