The Tube Preamp Cookbook Allen Wright

May 17, 2015 It is a preamp designed by the late Allen Wright. Vacuum State RTP3D preamp. Allen wrote a book called 'The Preamp Cookbook.

Has anyone out there built the Allen Wright (Vacuum State Electronics)FVP5A Single Ended Output Pre-Amp or his Super-regs? I'm considering gutting the innards of an AR SP-8 and utilize its switches, knobs in/out jacks and Power transformer etc. Any thoughts? Thanks in advance.

Wright when an opportunity arises here at AA. I have been using a 12 year old design of his, implemented in the Tara Passage FVP. It uses a pair of 12at7s in the phono stage and a pair of 12au7s in the line stage. Even though many of the parts are of average quality, this pre-amp is really something special. I have little doubt that his newest designs and implementations are superior. Halo 2 Modding Program there.

They are not inexpensive, even in kit form. They are arguably among the short list of 'state of the art' pre-amps. I then purchased his 'Tube Pre-amp Cookbook' which is a wonderful explanation of his philosophy and approach to design.

It is an interesting read and incredibly funny. I learned quite a bit about pre-amps generally and my pre-amp in particular. And it has caused me to long for the day that I might acquire a fully decked out Allen Wright designed differential pre-amp -- but such a unit would cost more than all my other equipment combined!

The other day of hearing Allen Wright's top of the line full function balanced preamp when I visited one of the guys here in Oz who manufactures them.

We listened to it using Allen's prototype forced symetry power amps (yes, they do actually exist). The combination was very impressive indeed. The preamp had a massive 74 db of gain - no noise whatsoever using low output MC's. It uses 6922's throughout and is built like a mofo. I now have much respect for this tube (I used to think 6DJ8's sucked).

It is more challenging than building it from a kit. The total cost for the whole linestage is around USD 850.00. The parts I used include Hovland for the output coupling caps, Elna Cerafine for the power supply, Tango choke for the power supply Holco for the audio circuit, DACT attenuator for volume control etc. For the shunt regulator, I bought his kit from a local supplier. My implmentation is a 2 chassis thing with the power supply separate from the audio circuit. I live in Malaysia so some things may be cheaper (e.g. Fabrication of chassis) while other parts are more expensive.

Sure you can build my designs cheaper than I sell the kits - I'm in business and have to keep alive, so my products have tohave regular commercial margins built in. Otherwise I'd have to do something else to keep alive and keep all my ideas to myself. Regarding the FVP5A design, the schematic comes with all new copies of the TubePreamp CookBook and can also be found on our website. It's been recently been with two of the TNT.com reviewers and they should be publishing it soon - they said I will not be unhappy with the review!

Posts: 9226 Location: Bethesda, Maryland Joined: December 11, 2000 I use a pair of SuperRegulators, built from factory kits but with some parts 'upgrades' of my own, to regulate 'plus' and 'minus' halves of the balanced HV supply in my Atma-sphere MP1 pre-amp.

I was a bit apprehensive going in, because I believed dogmatically in the sonic superiority of 'tube' regulation. I filtered the outputs of the Super Regs with separate 50uF polypropylene caps. I am very pleased with the results, and I can detect no nasty solid-state signature whatever. Also, the voltages remain bang-on exactly as I originally set them after many months of use.

Mission Impossible 4 Tamil Dubbed Movie Free Download. Phono + line). Note that this version I have built is not the FVP5A, in which triode sections of 6922 are used above and below output cathode follower stage. The previous version I built uses MOSFETs instead - the FVP5A should be better.

The preamp is incredibly excellent, especially the phono stage is the best I have heard (not heard many though). I built this preamp from scratch, not only because it costed much less than the kit, but also beacause I'm a DIY addict and I like to take the journey of building a project all the way long, from designing my own layout, to finding the best components I can afford and designing the case to my own taste. At the end, it was a great classroom completing this project and I learned a lot. For the Super Regulator (which I think is a must if you want to get full benefit from this preamp), I ordered it as a kit from Allen - it's cheap anyway and its contribution to the preamp's performance is essential. It's 1 1/2 year now that I'm using it and never had to readjust anything. For the future, I'm planning to built his RTP3C preamp - a fully differential design from input to output. This is highly acclaimed and I'm sure this will be the last preamplifier I will ever build.

IMHO, Allen is great and I surely can say that I trust every design he has put. Be sure also to get and read his Tube Preamplifier Cook Book. I learned a lot from this.
