EL34 is very famous tube and great for power tube amplifier. The circuit above is complete circuit contains tube amplifier circuit diagram and power supply circuit diagram. 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.

although you don't just pick up a few, unless you're running one of those 5 watt single tube amp's. You have to buy them in sets. Last edited:

The power supply is solid state. The filament supply is regulated at 6.3V using a LT1085 voltage regulator. The schematic is from the book "Build your own Audio Valve Amplifiers" by Rainer zur Linde. Circuit diagram - EL 34 schematics | El34 Se Amplifier Schematic Circuit diagram - EL 34 schematics "In electronics, a vacuum tube, electron tube (in North America), tube, or thermionic valve or valve (in British English) is a device controlling electric current through a vacuum in a sealed container. DIY Single-Ended (SE) KT88 / 6L6 / EL34 / 6CA7 Tube Amplifier. Here are some notes and photographs of a single-ended (SE) KT88 tube amplifier which I recently built.

Figure 2 shows the schematic of the tube amplifier I used for all the tests. Figure 3 shows the power supply (the power supply transformer for 120V mains is available from Plitron, #754709). Figure 4 gives the numbering and the colors of the wires of the toroidal output transformer and their positions on this round device.

[EL34 SE Amplifier] Analog Metric www.analogmetric.com 3 FEATURES • Two EL34, two 6SN7 and one 5AR4 tubes. • The first two stages use triodes of 6SN7 which are configured as common-cathode and cathode follower.

Kan tyvärr inte hjälpa dig men om vi lägger uppe ett schema här så kanske Jag har fasvändartrafo i min Weber AB200, ett EL34 single-ended

The driver stage unlike others does not use inter-stage transformer coupling or power tube like 300B, EL34 or 6L6.

Re: EL34 15Watt Transmitter. « Reply #2 on: July 23, 2018, 06:12:34 pm » My experience agrees with vk6zgo; the transmitter's frequency will be way too low for an efficient transmitter - if anything, you will receive the nth harmonic in your FM radio while polluting the entire spectrum from a few tens of MHz and up.

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. What I’m doing now is mating that preamp to an SE EL34. After looking at several ideas from other guys’ posts here and in AX84 I’ve come up with the hand drawn schematic attached.

Some things, like the actual EL34 cathode resistor value, will have to be determined when the thing is up and running, and measurements can be made. Note on 17th Mar 2013 : This board is now 2mm thickness for even better mechanical strength and reliability !! This is a bare PCB of a tube amplifier.

Firstly, I drew up a schematic of it's current lay-out, just to workout what is going on.

The circuit is interesting but i think it is hard to find the tubes. Schematic Diagram:… Read More » Other single ended EL34 designs commonly use between 250V and 400V. The lower end of the range will suit lower transformer impedances, and vice versa. In the following example we'll use 300V. Incidentally, although the El34 data sheet claims the maximum quiescent anode voltage is 800V, this applied to current production in the 1960's.

Last edited: JJ E34L also served me well in my high gain amp. Low end stays tight and well- defined at any volume level and with different distortion/overdrive/ 27 Feb 2018 Schematic can be found here. 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.
