Question for Llano owners or others w/similar amps


Have you replaced the tubes supplied w/your Trinity or Phoenix amp? And what have you replaced them with and from where did you get the tubes?

What, if anything, do you hear as improved?

Any recs. on good 12AT7 or 12AX7 tubes?

Thanks.

I have got some real joy with 5751 series. GE black plated extend well for both highs and bass and had a lot of life . They are cheap and the sound good I also tried some raytheon CK5751 but they a bit too transparent for me that.

Two cheap tubes with good sonic characters. Randy had the 5751 series on his old site listed as vintage sounding if that is of any help
The best tubes in my system were duMont labelled made in Holland 12AU7s. The AT and Axs made female vocals too "hard".
I owned a "Trinity", experimented with about (8) different tubes, if you can find them, Mullard "Gold Pin" 6922 -- best of all things, IMO.
