Croft preamp - 12BH7A or 6SL7?

[mathewf]

I have the 6SN7 version and it's really very nice indeed. Mine now runs 2x 6LN7's in the line, 1x 6SN7 as the middle and x2 6SL7s in the phono.

Hi Black Adder - Could I ask what do you mean by "the middle one" please? Also where you say "6LN7's in the line", do you mean 6SN7? Thanks.

lol, yes... sorry. 6SN7's

In my preamp there are 5 of the larger octal valves. So I have x3 that are 6SN7's, whilst two 6SL7's in the phono.

Actually, I have another question for you Black Adder if I may;

I asked you which 6SL7s you thought worked well in your Croft preamp when I thought I was going that way; which 6SN7s would you recommend trying?

I actually have a pair of Brimar grey plates, a pair of RCA grey glass GTs and a lone Ken-Rad waiting for a partner to try out...

Easily done, I made a very similar mistake emailing my dealer recently ..

For the line stage and the central valve I recommend NOS Brimar or Melz (OTK) and for the phono stage (6SL7's) NOS Sylvania 6SL7GTB's.

If you are going for 6SL7's in the line stage then NOS Melz.
