FINDING 6sn7 DESIGN

What is your budget?

See that way people could suggest parafeed output transformer coupled 6sn7 or choke loaded...type arrangement schematic..

versus a cap coupled schematic which is more affordable...

Cheers,

and you would like to build... what?

There must be many, many tube amp designs out there with a 6SN7 in them. What kind of amp are you looking for? Phono pre, line amp, power amp? A quick google search for "6sn7 amp" brings up schematics on the web for all three kinds of amp:

Bob Danielaks little 1/2W SE power amp with 6SN7 as power tubes can be found at http://www.geocities.com/bobdanielak/se6sn7.gif

The Foz line amp is a one tube line amp with feedback. It can be found at
http://joelist.free.fr/schematics/phono circuits/fozline.pdf (or here)

One of Steve Bench´s designs, a phono pre, is at the same site: http://joelist.free.fr/schematics/phono circuits/SBench417-6sn7phono.gif

I haven´t tried any of these designs, they are merely examples of what is out there.
We need focus here. So, which kind of amp did you have in mind?

6SN7 Plate Resistance relatively high,need the transformer or Cathode Follower.

5692 line amp post

If your looking for a line amp I highly recommend the one Frank designed for me. I just finished building/listening to it and I'm very very pleased with the sonics and performance that it provides. Granted I haven't gotten to complete the regulated supply that Frank designed for it yet. You will find this line amp very neutral and uncolored just as Frank said it would be. You won't go wrong with this one!!!

Hi,

Thank you very much for the compliments on the 6SN7 linestage.

It's just a rough sketch of what can be done and it can be perfected....

Still, I'm glad you like it,
