Tube Preamp, uses 6sn7/6sl7. With or Without Phono; With or Without Remote Volume,

I have known about the design in the link for many many years, and once nearly pulled the trigger on the idea of having one.

There are quite a few locations that this Amp Design will be seen under discussion.

A friend is nearly completed their version which will have VT 231 Tubes on board.

I will get my opportunity to receive a demo' in the not too distant.

This can be a very cost effective method to receive a very high quality Tube Pre', that should make the end user very content.

We are having dinner tonight, I'll ask about budget? and remote volume priority?

@elliottbnewcombjr 

I hope you are happy carrying out the Heimlich maneuver, it might be needed when you explain the SP05 and then the SLP 98 as the Budget Option.

I'll take a wild guess, that the Aikido Pre' is a design that is 4.5/5ths of one of the Cary models at at least a 10th of the cost. Add a really fancy casing and maybe a couple of extra $100 will be added.

I have last night been with a Cabinet Maker, who is to produce for me Two Boxes for my Balanced Pre' I am having Built. The Labour Charge is agreed at £250, I already own the Densified Wood, that is to be used.

I was hoping to be the first to have a D'fied Wood Carcass, but a DAC has already seemingly took that position. I'll settle for Second Place and the settle with the  concept 'Birds of a Feather Flock Together'.

As a side, I heard the Pre' as an almost finished Prototype on weekend passed, I am informed there are better quality RCA's and XLR's to be used, as well as a couple of Boutique Components, yet to be tried.

The Prototype was used in not owned system with a Value of approx' £70K, where the resident Speakers are Klipsch Jubilee Speakers. The experience of the Pre' in this system has been quite special, and the Builder made it known they were very confident there was a little more to be eked out.

The system owner wants one as well, they were 'Cheshire Cat' for the most of the demo'.

Both the Pre' Builder and system owner, had been to High End Munich 2023, and both made it known to all attendees, that not anything had been encountered at Hi End, that was a betterment to this Pre'. I will settle for that as a assessment.

How much do you have to spend ?   Radu Tarta one of the best vacuum tube designers in North America , he going to build me a 2nd preamp 

single ended or true balanced which adds a bit of extra cost his preamps either Lundahl or Monolith transformers , not cheap but his $6k -$7k preamp 

will be at minimum as good as anything at $20 k rule of thumb for Anything commercial brand 4-1 only 25% of the cost goes into the product including packaging ,the rest R&D overhead and markup.and Radu’s parts quality far superior  myself into modding over 20 years  Quality counts !!

Can't discuss 6sn7 preamplifiers w/out the mention of Don Sachs and Bob Latino.
