Hi I lovemusic2,
Glad you like the 6832 tubes. As with everything else, the sound depends on the associated equipment, and in my case I found the 6832s very good as power tubes, but ultimately lacking in the bass slam and impact.
I am happily using one as a driver, but I went back to my RCA 6SN7GTB tubes as power tubes. In the future I would like to try a pair of 6080 tubes as power tubes, but these require external power supplies since they draw 2.5A each. Once all the parts come in I am going to try and see how it sounds.
I know that there are people on the blog that tried various sub miniature tubes in the past. One such post came from Critical Bill, maybe in 2009, but right now I cannot find his post. Would appreciate it if somebody has information, as well as information on comparisons between different dual triode sub minis.
Somehow the sub miniature tubes do not have the visual appeal of the Coke Bottle tubes, but looks isn't everything!
These are mighty minis, and really the pinnacle of vacuum tube technology. For those of you who like to travel with the LD amp, they are good for 80,000 feet altitude (commercial air planes fly under 40,000 feet). They can withstand a 500G impact, and 2,5G vibration, as well as nuclear radiation. The amplification factor is 40.
Which one is the best sub miniature tube for the LD MKIII?
