mago...I know this forum is all about #26.....donkey's year ago I bought pairs of #26 and pairs of VT-25.....thinking I will try and compare both tubes.....I started with VT-25 first.....till now I am still working with my VT-25 (now VT-25A because of SQ....).....I have heard #26 built by many of my friends....but I am still sticking with VT-25A......
I wanted to start #26 myself....but keep postponing #26.....
Has anyone here, or you mago, had both experience, of your own built with #26 and VT-25.....and say about how they compare...?? please??
Cheers,
King

Help

I have a strange issue, after 2 or 3 hours of playback the #26 sounds but start to add to the song other not desired sound (exactly the kind of sound is like the end of a vinyl) once added this strange sound after 30 minutes or one hour start to sound a loud sound like 2 or 3kHz constant so I have to disconnect the preamp, any ideas to fix?
