Thanks for the feed back.

Here are some other questions. Your thoughts are valued and appreciated. What are your thoughts on the following statements? " I would never recommend a 6SN7 as driver for a 300B". and this one," I would not recommend a two stage approach". "Therefore, for me a three stage approach is best; it allows you the freedom of choice in terms of tubes and topographies. And the use of a passive volume control like a TVC or autoformer which hands down beats all active preamps, period. " Should these be my "goals" for what i want to accomplish? 1.Separate PS for driver2.Fixed bias3.AC heating4.Valve rectification5.Useful to get power tx with heater windings and fixed bias windings. And last but not least what does "nfb " stand for? THANKS

Thanks Maynard every little bit helps. I wanted to use aluminum for the base to mount everything on, now I know why to use it. Would it be ok to use a piece that is say an 1/8 inch thick for this?

Thanks for the replies Maynard, will do. How does this SE 300B stack up? KISS

Thanks for the reply Maynard, and I will heed yours and everyone else s warning regarding voltage. I only want to build one of these so I want to do it right. I realize now with what I want to accomplish with this project that it is going to be closer to $1,000.00 by the time I get done, but that is OK. Having said what you said regarding " 300b amp you linked has deficiencies" Is there another DIY project that can do the following. And not have any of the above mentioned concerns? > 8 Watts < $1,000.00 S.E.T. Integrated Tone / Bass Control 2 Inputs Is the 300B Tube the tube I should be looking at for what I want to accomplish? Will these Output transformers perform for what I need? Magnequest RH-80 Hammond 1640SEA Edcor CXSE25-5K one electron UBT-2 Electra Print (custom ordered very $$) And I was also looking at this one Transcendar How are Tone and Bass controlled in a tube amp? Is it possible to integrate a phono pre-amp into a tube amp? Meaning not a separate pre-amp but part of the S.E.T. amp. Thanks again everyone!

Greetings, I have been doing a lot of researching and reading. and have a few questions if you Gentleman might help me. 1. If I am understanding things so far, the Audio Output Transformer, Power Transformer and the Power Tube selection are the most critical components of a S.E.T. tube amp and will mainly determine the wattage and "character" of the amp? 2. What is the limiting factor or choices that determine if it is a 2 watt amp or a 10 watt amp, the size of the Power Transformer and type of Power Tube selected? I have pretty much settled on a S.E.T. integrated amp of at least 8 watts something along the lines of this 300B Single-Ended (SE) Tube Amplifier Schematic (6SN7 input) and would like to get some input on improving it as this design is from 1993. and last but not least what does " nfb " stand for? Thanks And Merry Christmas, Happy Hanukkah and anything else you might Celebrate at this wonderful time of year.

Do you have a build of this online?

Wdecho what 300B tube are you using in this setup? How many watts is you amp pushing out?

Go to the link in the above post and it will tell you how to decipher the numbers on your speakers.

Greetings, your English is fine. My Norwegian not so much anyway can you take a picture of the back of the cabinet, does it show a specification sheet? Check out this .pdf Klipsch Speaker info

Thanks for the response. So Monos are the way to go, do you have to house them separately?. Can you incorporate them into the same base (case)? And am I correct that a DHT is a direct heated triode? What is an IDHT ? The Poddwatt looks like a good place to start (is there a schematic anywhere) and then modify it to my liking. I don't like the boards, I would most likely go point to point.

Quick question on Monoblocks, What are the benefits of using and not using them? If I remember correctly wdecho you opted to use only one transformer in your build of the Poddwatts? Did you accomplish what you set out to do with this change? Has anyone else done this with success. Oh an a note to everyone, I'm not looking to spend 3-5 k on an amp. Probably between $500.00 to $700.00 for the parts and build it myself.

Those look nice, can you post a picture of the back showing the serial numbers etc. They look almost like my pair.

Is there a way to do a hybrid between the two?

I listen to Pink Floyd, Robin Trower, Black Sabbath, and Classical, orchestra etc. I have an SS amp in my signature that I Haven.t turned past 6 yet. Very Loud. I want this tube amp build to be able to give me some accurate music, and be able to feel it also.

"I have one PP tube amp that sounds more like a SET than some of my SET's," .......What amp is this one? My 2 DHT amps have a sound and soundstage like none of my other amps" What are these 2 amps? at the sacrifice of the quick bass of my PP. Not sure what you mean by this, please explain.

What amp are you using?

Well I kind of want the best of both. I like the thought of the sound of what a SET does. And I like the higher wattage of a PP. What would an amp that would be capable of this be like? Maybe like this? "If we apply SET design concepts to PP, using engineering practices aimed at achieving the best sound rather than the best specs on paper, the results can be astonishingly good". Are such amps available? " A PP amplifier using low Rp triode power tubes such as the 2A3 or 300B can get by with little or no NFB. For one, the triodes are an advantage in themselves, in both linearity and output impedance. Two, the front end voltage amplifer and phase inverter stages can be designed with much lower gain, if no NFB is present to reduce the available gain. Lower gain means lower distortion and lower output Z, so NFB is not necessary to attain these desirable properties. You end up with a much more linear amplifier, that has a simpler circuit with lower parts count and therefore less signal deterioration, and more air, breath, and vibrancy. See how much better everything gets when you set out to design it right from the beginning, instead of trying to fix it with NFB"?

So I am trying to decide whether to build a PP or SET Tube amp. I found the following information and wanted to get some feedback from the experienced here. What are your experiences? Are the following statements true? ADVANTAGES OF SE OPERATION . Less signal deterioration because of fewer signal path components Better detail and coherency, especially at low volumes . More open and airy sound DISADVANTAGES OF SE OPERATION Poor efficiency, with low power and high heat production Almost no rejection of power supply hum and noise, which necessitates more power supply filtering No cancellation of second order harmonic distortion (some do not consider this a disadvantage) (Usually) shorter power tube life Has speaker compatibility issues, is less tolerant of wide impedance curves and complex crossover networks Poor damping factor ADVANTAGES OF PP OPERATION More power (Usually) more authoritative and powerful sounding Better bass performance Fewer speaker compatibility issues Lower distortion DISADVANTAGES OF PP OPERATION Homogenized, uninteresting sound More signal deterioration due to greater signal path complexity More power supply intermodulations between amplifier stages, and other power supply anomalies Poor low level detail and dynamics
