I generally find DHTs have more clarity

Posted by andy evans on September 3, 2020 at 12:42:58:
I think I'd go as far as to say that the best DHTs I've used had more clarity and presence, and better instrumental timbre. No idea how the construction achieves this. Thinking here of 300b, 10Y, 46, 26 etc.
But this doesn't mean that all DHTs are better - some can suffer from various sonic defects from microphonics to higher distortion in some cases. And they're usually low gain tubes.
I've only used DHTs for the last 12 years but I'm starting to play with a few indirectly heated tubes as drivers for my 300b SE. I've been pleasantly surprised by tubes like EL84 and EL33 in triode, for instance, and intend trying some more like 6V6 etc. These medium pentodes and tetrodes in triode mode outclass all the 6SN7 kind of tubes I used in the past as driver tubes. Useful to have a gain of around 20 or more instead of DHTs mostly being a gain of 11 or less.
