6sn7 preamp schematic

Jumpers on the circuit board allow you to easily switch between 12V and 6V, allowing you to use both 6SN7 and 12SN7 tubes and expanding your tube choices. The 12SN7 and 6SN7 are sonically identical and differ only in their heater voltage.) 12AU7 tubes can replace the 12AT7 tubes to lower the gain.

The Raleigh Audio Line Stage is a state-of-the-art differential vacuum tube gain stage with integral power supply. This differential class-A triode parafeed output stage is a further refinement of the circuit, now in its fourth generation, first used in the excellent Raleigh Audio Line Stage detailed in the November 2004 issue of AudioXpress.
The latest result of Had's fascination with the 6SN7 is the Cary Audio SLP 05, the company's newest line-level preamplifier ($7500). In fact, the SLP 05 uses eight of them: not quite ENIAC, but more than I'm used to seeing in one place. The SLP 05 is a two-box design in the usual sense: one chassis dedicated to the power supply, the other to ...

But this does not make it a bad tube. If the circuit is designed for it's parameters it is a great performer and it works well in unison with the 6SN7. For example as first stage in a phono preamplifier. Correctly implemented the 6SL7 gives a nice warm and smooth sound. As it does for example in my Octal Preamplifier Mk1. The 6SL7 has also been ...
They also have enough grunt to be a really good 2w PP output tube, way better then a 12AU7. 6Sn7's are my preferred low gain audio tube. 6SL7's can often match in circuit gain of a 12AX7 because of lower plate resistance, all depends on the following load. 6SL7's have "round, slightly soft, organic" feel that none of the 9 pins can match.
Tube Power Amp Schematic of Triode Preamplifier with 37 and 76 Pre Wartubes. The American prewar-types 37 and 76 have the same heater (6,3V / 0,3A) and quite similar plate-characteristics. So if you choose the design carefully you can simply change the tubes. The operating-point is chosen in a area with most parallel curves: Ug=-7,0V / Ia=3mA ...
SUGGESTION. If you already have this 6SN7s at hand and are willing to make it, just take a quick look at the RPA preamp on my webpage www.tubeaudio.8m.com. The line stage of the RPA uses ECC82, but since the sub is the same, you can copy all values and make it with the 6SN7. It will sound way, way, better.

6. I found that I could coax more clean headroom out of the unit by using 6SN7 tubes for the preamp stages instead of 6SL7 (think: 12AU7 vs. 12AX7, sort of). For bass, I like clean headroom. I looked at the signal from input to output with an oscilloscope and found that clipping was most likely to happen first in the preamp stage.
Fig 6 schematic is a very basic triode amplifier using one triode of a pair inside a 6SN7 twin triode. The 3.4mAdc generates +4.8Vdc in R4 1.4k, ie, Ek = 4.8Vdc. The grid bias Vdc is same as 0V rail because of biasing R2 100k from 0V rail to grid. Therefore the grid is -4.8Vdc below the cathode Ek, and Eg1 = - 4.8Vdc.

6SL7 / 6SN7 JE Labs Phono Preamp. Page 1 of 2 [ 13 posts ] ... I will give a try on the circuit and measure the voltages at the 6SN7 while playing with the potentiometer.
Hi, I've been a member here for about 4 years. I've restored a half dozen amps and built a few kits and now I want to build a 6SN7 line section preamp from scratch using a lot of the parts I have on hand and try to do it for under a $100 I've found a schematic for "The Blue Velvet' on line that I think will meet my criteria.
Octal base version of type 42. Moderate power output rating—9 watts max. (single-ended Class A circuit); 11 watts max. (push-pull Class A circuit); 19 watts max. (push-pull Class AB 2 circuit). Available in metal (numbered "6F6"), shouldered glass ("6F6-G"), and cylindrical glass ("6F6-GT"). Sometimes used as a transformer-coupled audio ...
Phono End preamplifier Feb 7 st, 2009 . INTRODUCTION. This project born to be a no compromise phono preamplifier without budget limit. These are the main characteristics: Only 2 stages Only 2 vacuum tubes on the signal path No capacitor on the signal path (escluding RIAA network) No resistor on the signal path (escluding RIAA network) Less components of any other design Output impedance and ...
It does not have to be a complex circuit- in our UV-1 there's only one tube per channel and 4 resistors! Audio Research makes respected preamps, but I would expect many of the 6SN7-based preamps on this thread to keep up with any of them. This is not an attack on ARC, its simply a statement of how well 6SN7s work in line stages!
