To make the stereo channel amplifier, build the similar amplifier circuit only and connect to the power supply using parallel connection with another same amplifier. I’m working on some ideas for a single ended EL34 amp and have a few questions. Would greatly appreciate your input. The preamp is pretty much nailed down.

The SE tube amplifier design has been based largely around Mikael Abdellah's KT88 SE Tube Amplifier design from 2003.

Puedo sustituir los j201 por 5457? qué tipo de modificación adicional se le debería hacer al circuito ? Reply  These matched tubes give your amp a focused, aggressive tonality, with plenty of low-end punch, rich midrange, and detailed highs. Great for all playing styles,  EL34.

Schematic is from Build your own Audio Valve Amplifiers by Rainer zur Linde. The output power from a SE pentode stage will be roughly half the anode dissipation of the valve, so we'll need a valve capable of 20W or more. There is actually a wide range of valves that fit the bill, but the most common for guitar use are the EL34 (25W), 6L6GC (30W), or a pair of parallel EL84s (24W).

Oct 31, 2002 These considerations lead me to choose EL34 as my output valve. I want it to behave as closely as possible to a triode without sacrificing more  Nov 11, 2009 Hello!

Introduction Ever since building the 2W single ended tube amplifier, I wanted to build something better, something that is considered a good… This is a bare PCB of a tube amplifier. Each channel makes use of a single low noise tube 6N11( or Russia's 6Н23П or US's 6DJ8)at the input and proceeded by a power tube EL34 to accomplish power amplification. Depending on whether the output transformer to have center-tap or not, the board can be connected in either triode, ultra-linear or pentode mode of operation. EL34's is an economical method to achieve high quality sound with a minimum of driving stage components. The Svetlana EL34 is manufactured with the original Mullard design in the Svetlana factory in St. Petersburg, Russia, and is designed to be a direct replacement for any EL34/6CA7 or equivalent.
