SET12

See tube amp question! for a review of his review, sorry for the inconvience wrong post! Thanks

Have a Happy Fourth Everyone!

Speakerfritz is right of course but I'll will go one step further because there will be a high noise floor in my experiance with what looks like the same amp I set up for a friend. You may have to use some series resistance to get the noise floor down starting at 100 ohms and work in either direction I used some Radio Shack non inductive 8 ohm 20 watt resistors yes their big but cheap you should be able to pick up jacks as well there. If your using it for CD I would recommend the variable out on the CD player. I think you will find that it will literally blow away the solid state headphone output from your player as it did my 2000$ Sony ES player Headphone output. Enjoy! SET12

Hey Thebes! since you've messed around with your 2A3 would you care to mess with it some more I think I could help you get some more wholp out of it! The bass out of a 2A3 can be even better than a 300B if you can post a couple of pics like inside the chassis post a schematic if you have one or even e-mail me! Just another Wizzard with his own bag of magic[*] SET12

Another Photo, This is a pic of myself holding an 833 in my hands, using my car battery jumper cables and some series resistance to light up a 833 in my garage. here is a link to my local club web site discussing the 833 and other transmitting tubes with a lot of pics and links. http://newaudiosociety.com/cgi-bin/yabb/YaBB.cgi?board=amp;action=display;num=1137773606

Yes they are and heres a link for anyone wanting to know more about this man and his amps. http://www.6moons.com/industryfeatures/josh/josh.html

Have you seen these?

Another moment in time!

A 100TH single ended amplifier Thanks Mavel for the post on posting images saves alot of time!

Thanks Tony! And well said! And its the same here! SET12

jt1stcav, Very nice looking system! I to use the GZ37 rectifier! Raptorman, Yes the picture is the same amplifier I also have some pic's of his 100TH amps using the same style of build but on one chassis/monoblock SET12

Sunnysal Thanks, My Humor is what some people refer to as dry! I'm lucky that I have a women in my life that finds me even remotely funny! But she does. I usually don't get envolved with humor cause I don't think I'm very good at it or even understand it at times I tend to be more engineer than a smiling consumer and even though I'm not an engineer I might have been one if things were different in my life I have some electronics training and work in the industry my strenght is Vacuum tube design which one of my former instructors told me that I knew more vacuum tube theory than any instructor in my school and this instructor was a Radar tech working with tube circuits in the Navy of course I don't know it all but I know enough to design circuits from Phono circuits to Power amps and preamps Thanks again! I hope this gives a clearer insight of who I am. SET12

I have to admit that there are not alot of SET amps that are capable of produceing the dynamics that I like but they do exist the Transmitting tubes do well but not always and some are pretty bad. Most use the old classical design approaches and can yield still some glorious results but not necessarly the most dynamic results my own design is anything but a classical one. A few years ago I attended an audio show in Lima Ohio and had a very good time, I got to meet Dr. Bruce Egar who I feel is the current worlds foremost horn designer even he prefered the PP design vs a 10 watt SET from the guy he tours with I think it was Brenner Audio or something like that with his 107db efficent horns. I also got to hear several pieces of Audio Note gear for the first time from the largest North American dealer of it I think I don't know what was wrong but I was not impressed with what I heard and that stuff is suppose have such a reputation. I can also say that I have had people of all ages and experiance here in my home and fun part is the 20 yr olds hearing RAP music from my SET asking "how can that do that?" after they tell me about their 1000 watt car stereo and I tell them "oh! this is just 5 watts" the look on their faces is priceless. So I can understand your experiances. SET12

Raptorman, thanks for trying, I don't remember e-mailing you but maybe! any way I to struggled for a while getting pic's on forums, this is the site I use to host I haven't had any issues with it. http://www.imageshack.us/ Hope you can still get the image to me Thanks Dan

Edwinr the pic's are of a 2 box stereo 300B amp one Box is for the power supply. Thebes I to use HexFreds I tried them in my power amps and still prefered the Mullard GZ37 rectifiers that I use I prefer the GZ37 over the 5AR4 most of the time I think because of the 3 amp filament has greater emission v.s. the 2 amps from the 5AR4. I use the HexFreds in my phonostages. SET12

This is a photo of my own 811-10/572-10 project 10 watts peak or 5.5 watts RMS Class A2, bias is 0 volts the output transformer in this picture is a 6 lb Hammond I now use Hammonds 28 lb with this chassis for even better sonics they replaced the 6lb Iron with 11 lb version and recently have came out with a 10K primary that would mate well with a 16 watt 833 project. These amps where inspired by an 811 project featured in Glass Audio around 1996 and my first listening experiance with the Cary 805 single-ended mono blocks equiped with the 211 transmitting tube in 1991 and other than the tubes they do not resemble the original project they exceed it. The whole idea of the Glass Audio project was to give people a taste of the big Transmitting Triode Sound with out having to spend a fortune I can tell you that these were built with simple hand tools and grey box's from Hammond they now offer powder coated black box's that are very nice.

Yes More pics?,bring em on! Greg This is DIY at its best and I might add 1/10 or less of manufactured prices you don't have to go to these lenths to get involed with DIYing it there is a great DIY site called www.diyaudio.com with some 50,000 members covering every topic of which I am a member of. I might add that the 833 tube is just 150$ and there are 4 versions including a graphite plate version as well a guy by the name Bob Daniellak has done a fairly simple Class A2 16 watt amp with this tube with very good results you should be able to find his schematics if you want to take a look. Power Suppy underside Underside of the 833 chassis

I was thinking of this amp but I guess its a 300B never the less a giant!

When I put them in my Single Ended 2A3 Amp which I had previously installed a choke coil I kind of felt like it helped some areas and maybe took away something I liked a little also but I left them in anyway and have been OK with them in this amp" Have I got a 2A3 to show you! I'll try and get it posted tommorow. SET12

Steamer, Do you mean the 833 two chassis Mono Block with the wiring connected to the tube? If so the bottom of the tube are filaments connections, The top is for the grid and plate I have additiona pics if you'd like to see them! This not my amp but just an example what DIYing can do! SET12

Thebes, Thank you for the compliment! What is it that caught you eye?

Thank you! Paul You would use the Thorens Phono straight in into any High level input that includes tape inputs as well. Personally as a phono stage Designer your more than likely to do better with, an outboard phono stage, their are many to pick from the Thorens that I think you said is inside your table maybe very good! I once heard some Thorens Electonics at a show and thought it was perhaps some of the best solid state I had ever heard I told A High Level Thorens representative that who ever was their designer was to never let him go!

Paul, If you liked the Cayin stuff you may like this beauty it has alot going for it including a slow turn on rectifier tube along with many nice features including remote! Its from Eastern Electric Audio Company

Speakerfritz, Check out this Eastern Electric out this is pretty nice one of my local club members was looking at this I love rectifier tubes, slow turn on! and remote! http://www.easternelectric.co.uk/easternelectric/M520/index.htm
