@tkcha Cha's amplifier is a very robust build centered around the 845 DHT/211 tube, and will be using EL34's (also capable of a KT88) to drive the large voltage/current swings needed for the Input of the DHT. A 6SL7 will be the input stage, then the Pentode driver stage, and lastly the power tube. We're using Electra-Print output transformers and a choke (capable of handling 5 kV swings). This amplifier uses many upgrades parts including all Vishay chassis-mount resistors, Audyn "True Copper" caps and independent power supplies for both the driver/pentode stage, the 845/211 power stage, as well as DC on the DHT's filaments. All will fit neatly in a hard-wood wrapped chassis with mirrored-aluminum as the finished top plate. Aric
Tekton Double Impacts
Anybody out there heard these??
I have dedicated audio room 14.5x20.5x9 ft. Currently have Marantz Reference CD/Intergrated paired to Magnepan 1.7's with REL T-7 subs. For the vast majority of music I love this system. The only nit pick is that it is lacking/limited in covering say below 35 hz or so. For the first time actually buzzed the panel with an organ sacd. Bummer. Thought of upgrading subs to rythmicks but then I will need to high pass the 1.7's. Really don't want to deal with that approach.
Enter the Double Impacts. Many interesting things here. Would certainly have a different set of strengths here. Dynamics, claimed bottom octave coverage in one package, suspect a good match to current electronics.
I've read all the threads here so we do not need to rehash that. Just wondering if others out there have FIRST HAND experience with these or other Tekton speakers
Thanks.

@charles1dad - This is a very robust power tube using very high voltages and requiring a very heavy voltage swing at it's grid to drive it. 30 watts is the absolute maximum this tube is capable of- and that's running it at it's absolute max specs (not a good recipe for reliability or distortion). The sweet spot for this tube is between 18-22 watts, and this amplifier will have fully user-adjustable bias controls to fine-tune the amount of current that it draws. |
