The 112's on my amplifier were made in 1926. I think they sound good but I actually chose them because I wanted low gain. Regardless of that there is a certain different pleasure to be gained from playing modern recordings using tubes made over 80 y...

The references to inertia and lightness are not to do with how a DHT works electrically but to do with how sounds reproduced by them 'can' be ie without smearing or overhang. Its a characteristic I hear in live unamplified music and one that is endea...

By 'lighter' I mean that the DHT amplifying stage subjectively has less inertia and is able to change direction more quickly. I suppose nimble might be a better word. At the moment I usually do use the amplifier 'full range'. (My speakers will no...

What do you mean by 'sonic verdure'? Do you mean virtues? If so I would say that they typically offer a lighter, unfettered presentation of timbre & dynamic range across the full frequency range provided that the HT and LT supplies allow them to....

Hi Romy, I currently use a 3 stage transformer coupled amp with 112's, 71a's (as drivers) and your favourite 300B output valves:-) I'm not sure whether I'd go back to a capacitor coupled amp. I just acquired some Tango NC20 IT's to replace the NC...

What you say may be true. I'm not sure there was an amplifier available in the mid to late 1980's that would have been suitable for these. They did get good reviews but I suspect that some of this was due to awe inspired by the technical achieve...
