Thats really not the right way to look at it. When i drop $35k for a pair of power amps, or $10k on a flatscreen, those products had better be absolutely perfect in every single way, and stay problem free for a very long time. It is the reason why wilson can get away with charging $150k for a pair of speakers.

If he went that far for the easy bias, i don't see any reason why he did not finish the job, and have a little single chip micro do the job automatically every 30 minutes, when there is a between the track silence. Servo bias with a 1 minute time constant is way easier and cheaper.

You have to adjust the dc output voltage for each of the 4 output tubes. Absolutely no difference between that and a he90 or aristaeus. My all tube amp uses self bias instead, and requires no output bias adjustment. Although there is a phase adjustment that is set basically once for the life of the amplifier. The blue hawaii has dc feedback, and for a range of different tubes the adjustment needs little to no adjustment.

I have personally only seen a picture of one such unit which clearly had pop-rivets holding the bottom on. I have a copy of that picture somewhere, and don't really want to look over 5 computers to try and find it. From a repair standpoint, pop-rivets are a really bad thing, as much of the time, drilling them out causes some damage to the paint.

I have to bring out the bullshit meter, and its once again pegged at 11. I know of no other audio manufacturer of tube amplifiers that rivets shut their cases. Not conrad johnson, audio research, cary, VTL, EC, Woo Audio, atmasphere, the list goes on and on. Not even Mcalister who by all acounts should actually be riveting shut his amplifiers does so. Many of the above amplifiers have voltages and currents far in excess of what is in any of the DinglePower amplifiers. Mikhail told me more than 2 years ago he was applying for patents. Well if that was actually true in that amount of time the patent application would have showed up on the pto.gov website. Guess what, i checked, still nothing. Other than possibly the triangular layout of the tubes that might result in a design patent, there is absolutely nothing patentable about any of the DinglePower amplifiers. And the schematics are certainly well known and have been around for a very long time. If someone was going to pay for say a bigger transformer, or special caps, all of which are pricy upgrades, should they not be entitled to verify that they got what they paid for. In fact for someone who spent $10k+ on an amplifier, should it have significant flaws right out of the box. Not even Ray Shambles does such a thing.

Lets say you are using el34's (6ca7) the filament power is about 8 watts, and the plate power is 8 watts PER TUBE. If you can hold your hand to the glass part of that tube after it has been on 10 minutes, then something is clearly wrong with you because i just measured the outside temp of the glass bottle to be about 165F. Does not really matter who makes the amplifer, and for what purpose, but anything with 6ca7,6080,kt88,6550... I dare you to touch any one of those with the power on.

Do you really think that the ES-1 is going to be any different. Some versions of the ES-1 use absolutely the same output tubes, and same number of them. If you bias each tube at 10 watts (half power), plus the power of the load resistors, plus the power for the filaments and the efficiency of the power supply, no matter what you do you are at 100 watts or so of total heat dissipation. Which is nothing compared to a big audio research, or atmasphere amp, which dish out at least 800 watts of heat.

each heatsink dissipates 20 watts. The heatsinks are more than large enough Almost double the size of the previous heatsinks. The rest of the chassis runs very cool, and the power supply just a bit warm. The tubes run as hot as tubes normally run.

Someone should post it over at that other place. I'll bet it lasts no more than 10 minutes. if you believe this table http://www.sensiblechoice.com/schabt.htm and if it is a small cat, then 4 or 5 feet of headphones might actually fit and stick out each end.

The original site is not safe for work. My site is certainly safe for work. The question is whether it is faked or not, and if it is faked, then how. Sure looks real.

Most furniture does not plug in the wall. Most furniture is not on perpetual back order. Really good furniture lasts a very long time, especially when not abused. The one couch i'm not replacing is 25 years old, in absolutely perfect shape and very comfortable. The dogs sleep on it much of the time, but evidently it does not taste good enough for them to chew. Really need a 100 inch lcd panel for the serious media room. Too bad they are not available yet.

Yeah i know, the dogs when they were puppies... But the father in law with that crap he used to put in his hair dissolved the finish of most of the top of the leather anyway. So basically a completely new upholstery job is necessary. New couch and new chair very soon.

Lets see, earl points to a schematic over at headwize that has no input cap, no interstage coupling caps, but does have output caps, then he says that the extreme is different from that because it has no caps. I think his intent to deceive is quite clear. I am an asshole. Damm proud of it too. Earl should look in the mirror sometime.

billy is that the best you can do after sleeping to 2pm on a sunday??

Something has been bothering me all day about earl and his sack of spinning shit. See this is the complete pile of bullshit that started it all on page 7 First of all its the Woo3. Which is exactly the same circuit on headwize. WHICH HAS NO COUPLING CAP EITHER. Which is exactly the same as the Darkvoice, which is exactly the same as the HD300. which is exactly the same as the EXTREME. Don't mince words earl you mention direct coupled. That refers to an output stage. Your spin into coupling cap will not be tolerated. Your further spin into interstage coupling cap will also not be tolerated. If you are actually telling people that the EXTREME is direct coupled then you are lying your fucking ass off. Stop it. There is no reason for it. Pretty soon we will all be calling you ray junior.

The ZD is the ONLY amp out there with that particular topology. It sounds different from the rest. I happen to like it. Some have said there are manufacturing defects, this i do not know. I definitely have experience with the 6c33's and my mig amp runs them at full blast, and has all the problems associated with running them at full blast. Thinking heavily lately about a mig3 amp which has a topology similar to the ZD except that it is fully dc coupled input to output. A beast for sure.

If would heavily depend on the parts used. In general i think that 4 smaller caps in parallel may have 20% or so less inductance and likely have a bit less resistance too. The DA is likely to be about the same. Blackgates and Cerafines definitely perform very differently. Thats what a really good LCR meter is for. I have a couple different ones. Of course the absolute best output cap (now everybody all at once say) NO CAP WHATSOEVER. Its certainly possible. I have 2 different prototypes that prove it. The chances of something like that ever coming out of SP is pretty much close to zero. And for Ray Shambles, it approaches negative infinity.

Earl you are SO full of shit. Of course the output caps contribute 90% of the sound to the overall sound of the amplifier. Reason they have to drive low impedances, 32 to 300 ohms. Therefore they have to be at least 250uf. Unless you buy those honkin big things that EC uses that are the size of a baseball (nope earl, not the power caps) you are going to have to use electrolytics. Those things EC uses have a silly price attached to them. One of the very few things mcalister gets right (one of the VERY few) is to use very large motor start oil caps as the output caps. Now many companies use just one really big electrolytic, mikhail's sthick is to parallel 4 or more smaller ones to get to the same number. Typically mikhail uses 450uf or more. All electrolytics have significant inductance, dielectric absorbance, unidirectional performance... You name it. The non-extreme singlepowers are all white cathode followers and as such have 2 interstage coupling caps per channel in unbalanced mode. These caps see a load impedance of several hundred thousand ohms minimum. So you can put really good caps here. Teflon, silver foil, you name it. Still the effect of those caps makes is very small compared to the output caps. With respect to the quad 5687 amp, It is sometimes hard to determine what is going on inside an amplifier without really good pictures. So if i made a mistake based on virtually no information, and lots of dis-information then i'm sorry.

There are no interstage coupling caps. This is a true statement. There ARE output capacitors. This is also a true statement. The next pile of bullshit out of your mouth earl and i post every single singlepower inside picture i have, including schematics. This will not be good for mikhail. This will reverberate around for 6 months or more. It will do significant damage. That i will promise you. So pull your head out of your ass, call mikhail and let him decide whether or not you want to continue this line of bullshit. See billy... ray shambles is not the only one i pick on

Two resistors to reduce the hum will have nothing to do with reducing the distortion. Definitely not what i'm talking about. Yes the extreme uses 2 sections of each power tube in parallel for twice the current. As much as you are going to get out of a single power tube unless you change to 6c33's. Different parts, sure, but are they better who knows, they do sound different. Now power supplys,that is where there is a significant difference. Note: the Zana Deux is not a cathode follower.

Do tell. Its not really like it is super secret military technology. Or is it? Two different people have published the same kind of thing, but are using it for gain sections, not for power followers.

Since the proton type of tube does not exist in this universe then EITHER 1) A DC coupled tube output section can only exist with multiple power supplies AND lots and lots of solid state help. OR 2) Be fully balanced where both outputs are lifted many volts above ground (typically half the B+ rail) AND significant amounts of solid state help to maintain the difference between the outputs at zero or lots and lots of extra tubes and extra power supplies to accomplish the same thing. (generally considered to be unsafe) OR 3) Be fully balanced with a circlotron topology with a minimum of 6 power supply voltages, 4 of which must be fully isolated, plus fillament supplies. The extreme is none of the above.

The output stage of the extreme is NOT direct coupled. There is an output cap just like every single other cathode follower setup except for my servo controlled bamaslama. That cap is where all the changes in sound happen. The interstage coupling cap has much less of an effect on everything, especially if it is a really good cap. Its all about the impedances involved. Big difference between 1 megohm and 32 ohms. Besides which a direct coupled output stage requires a power supply with both + and - voltages and with high gain input tubes, that requires a seperate power supply too. Last warning earl, knock off the bullshit. No need for it. Now as far as the time machine, things for me are going really great and have been for some time. I have no need for a time machine. Now maybe in 20 years i might need one then i'll be able to whip one up in a weekend.
