Running on a B+ of 600-650V, it puts out around 8 watts. It presents a primary impedance of only 1600 ohms and benefits greatly from this low winding ratio. a high supply voltage of 450V (at maximum power output), and a quiescent current of 45mA per EL34 pentode tube. Top. GIF In many PP amps I have used fixed bias, and in 100W ULAB amp with 6 x EL34 I have used 6 adjust pots. The amplifier worked from 1954 to 1989, whenever and went off, with an average lifespan of 15 hours a day.

The EL34 was the 1952 successor to the very successful EL37 and both share a high value of mutual conductance 11. 5A@ 6. It has an international octal base (indicated by the ‘3’ in the part number) and is found mainly in the final output stages of audio amplification circuits and was designed to be suitable as a series regulator by virtue of its high permissible voltage between EL34 Single Ended Class A vacuum tube stereo amplifier. And like all of our kits, we don't just hand you a schematic and wiring diagram and throw you to t EL34 PP Amp : EL34 PP Amp: PP amp Index Power Supply High Voltage Driver tube Negative supply Heater for Driver and Output Tubes . Mail me at [email protected] EL 34 tubes . It also offers 4 line inputs, a nice aluminium remote that controls volume setting and muting (not the inputs!) and the usual two sets of speakers outputs for 4 and 8 Ohm connections. 2Vrms to make 37Vrms at anode, so EL34 THD is very low with the high ohm value of its RL, while Ra of EL34 is only 1k4, so it is a low Z signal source and bandwidth will be wide enough. this schematic is for pcb fabrication p/n 0079091000 and pcb assembly p/n 0079090000. $75.
