Tekton Double Impacts

Charles,
I'll let Aric discuss the technical aspects of the build as I'll most likely get it wrong, but yes I also believe he will create what I'm looking for in an amp. Thanks to you and your Frankensteins I had a lofty goal to aim for. I look forward to having you hear my new system....and bring more cd's as I love hearing music I'm not familiar with. I'm really enjoying the music of Bobby Hutcherson that you turned me onto.

Thanks Greg, I enjoy trying new music and I'll be ordering cd's from your list later today. 

Im as surprised as you are that I went this new build so soon. I was so focused on either going with the KT 120 or 2A3 amp that I never really considered a 300B. Aric's KT 120 gets me a good way towards the SET sound I so loved from the Frankensteins but I decided to get all the way there and when Aric suggested he could build me a no holds barred 300B I jumped at it. At times I'm quite deliberate in my choices but I'm often very spontaneous.....and this was one of those times. My dilemma now is what to do with this exceptional KT 120. It's too good to not use, it's probably too new to sell at a decent price, so gifting it to my son makes the most sense.....the spoiled brat. Lol. Not really, he's a good kid, if one can be considered a kid at the age of 31.

Tom I saw your system, how far are your listening chair to the speakers, and what is the distance between speakers....? Thank you

Tom,
I'm also a fan of live recordings  (especially jazz) here's a recommendation I think that you'll enjoy very much.  "Roger Kallaway At The Jazz Standard " It’s a 2 CD set. 
Kallaway piano
Russell Malone  guitar 
Stephon Harris  vibraphone 
I don't recall the name of the bassist  (but he's good 😊)

Top tier jazz musicians in a very good venue. Wonderful music, these gentlemen can play! Your fine system will definitely  extract the musical  beauty of this recording.

Hi all, I just wanted to briefly outline the scope of Tom's 300B SET build. It will be a single chassis stereo amplifier, using dual 5U4G rectifiers (both in parallel to provide double the current capacity), and a 6SN7 per channel for the input and driver stages. Single capacitor coupled output to the 300B, running the 300B at 66% dissipation for longevity and to produce 8 watts per channel. A choke-filtered power supply, and robust filter stages after the rectifier will produce a very black background. In addition each 300B will have its own independent filament transformer. DC on the 6SN7 filaments will provide low noise for the input/driver stages and reduce the overall noise floor to nil (generally not an easy task for a 300B based amplifier). All power resistors will use Vishay chassis-mount/heat sinked units to reduce internal heat, and essentially the entire amp will be built to provide twice the current that the circuit requires for lower heat/better reliability. The amplifier weighs close to 50 lbs, and will be 17" wide x 12" deep, x 3" tall (minus the wooden side rails). Price is $3,600 including EH 300B power tubes, (2) Sylvania NOS 5U4G's, and (2) RCA 6SN7GTB's for the drivers. 2 year warranty on the amplifier as well. 

Hi Aric,
Thanks for the additional information.  This custom made 300b  amplifier driving the Double Impact SE will be a fantastic pairing is my prediction. 

Do you have an opinion regarding electrolytic versus "film" capacitors in the power supply (filtration) and is one inherently better than the other ?
