RE: Another vote for the 12bh7 used as cathode follower ...

I think i expressed myself badly.

I am waiting to receive a tube buffer for the dac and this has only one 6922 or equivalent.

The preamp instead is an old Croft Micro ...
This preamp has two 12ax7 for phono and just one 12au7 as line stage (a buffer).
I took out the two 12ax7 and replaced the 12au7 with a 12bh7.
I liked the sound of the line stage section with the 12bh7 in place so much better.
More powerful, crystal clear ... very very good even if i guess the circuit is designed for a 12au7 of course.
And still the sound was much better to me.
So they are two different cases.
Kind regards,

As I understand it, the tube is only used for the line out section... - Ivan303 06:03:03 03/08/14 (3)

I have no idea what you are talking about - bullethead 06:20:04 03/08/14 (2)

What, that black spot on the right side of the front panel is NOT a headphone jack? - Ivan303 07:02:52 03/08/14 (1)
