A high gain triode such as ECC83 presents a rather high input capacitance. A total of — pF at the input of a ECC83 is rather common, depending upon type of socket, build of tube and component lay out. The input capacitance of a triode being the parallel combination of the grid to anode and grid to cathode capacitance.

The distortion is quite low, due to the relative high amount of feedback set by the ratio of the k and 1k2. The phase inverter is not quite the usual paraphase in the sense that the cathode resistors are not decoupled Bypassed by capacitors. This provides local feedback to the paraphase, the advantage of this is better linearity, which equals to lower distortion.

The output stage is straight from the book. The V80 is pretty much the same as V There is less feedback at the input cascade and the grid to cathode capacitor is omitted. The feedback scheme is the same for all the three amplifiers. The negative feedback is not global and neither does the two feedback loops interfere with one another. That is good. A switch is used to select the load impedance and this switch sets the used feedback resistors as well.

The V60 was one of the last valve amplifiers from BoFa. The valves used in this, is unknown at the time of writing. All three amplifiers in this vignette was supplied with a EM84 magic eye for signal monitoring. BoFA cinema sound systems. Pictures by Andre Hanekomwhom also owns the amplifiers. Wonderful indeed. Absolutely as British as English tea, bacon and scrambled eggs. But this PYE has a few significant twists about it. First it is noted that the input twin triodes is coupled in parallel.

This slightly reduces noise, but more importantly cuts the output resistance in half, thereby increasing the upper roll-off. The long tail circuit is conventional and so is the output stage. But this amplifier is equipped with current feedback via the 0. But there is more, it is provided with a regular Voltage feedback loop as well. This actually equals to power feedbacka very rarely used feedback method. I would suggest to increase the transfer capacitors between the stages in order to avoid capacitor degeneration.

Quite a nice and respectable amplifier. This amplifier is a splendid exploration into minimalistic design. These were buzzwords at the time — we keep forgetting just how expensive parts were back then.

A very different approach from nowadays. The circuit is an abbreviated Williamson and much care had been Album) in order to optimize the amplifier with as few components as possible. It is still a very good bid on a low cost high quality amplifier. In my experience EL84 is one of the most satisfying power pentodes to work with, in that it is so easy to entice it to do its best. It range from a charming musical sound to a convincing High Fidelity reproduction without much effort and even vibrant high end — if care is exercised.

It even sounds fabulous good in guitar amplifiers. It is a very tolerant pentode — almost as versatile as a triode. The EL84 was made by Marconi as N and the mill. I believe that 6P15 is a close equivalent too. There is not many near equivalents to EL84, but there is a few. Certainly that meant that the max. The predecessor was Philosophischer Irrtum - Strom & Wasser - Anticool (CD a Rimlock socket, power pentode.

A good one actually……. But this is indeed a bad mistake. I believe that the mistake originates from the exception to the practice of the European type number codes. Usually the first letter in this code refers to the Heater voltagethe second to the number of electrodes, first digit refers to socket type.

Philosophischer Irrtum - Strom & Wasser - Anticool (CD Max screen grid 2 ratings are way lower than the ratings for an EL Do not confuse these valves with EL The PL84 my favorite is more difficult to use than EL84, but it is actually possible to achieve an even better performance. Just do not design with an EL84 in mind. A voltage of to is a common practice.

If you can not locate a genuine Telefunken PL84 at a reasonable price They seem to go for 2A3 alike prices these daysthe Mullards are a close second. Have to be said Album), that they are all good. The two pentodes does not work in unity in that circuit. Circlotron example with the PL84 family. Obviously a quartet twice as much into Ohms. The amplifier above is capable of driving loads as low as Ohms and it will still be suitable up to some Ohms.

The ideal load will in theory be around Ohms. As it is quite difficult to obtain loudspeaker of such high impedance — except for headphones — it will be much better to substitute the two uF capacitors at Album) output with a genuine output transformer.

In fact only one capacitor is needed, provided it is an bi-polar one. This will provide better regulation as well. The cross coupled input phase splitter is a matter of choice.

Any phase inverter will do, but it is of advantage that it is a balanced type: paraphase, longtail or cathode inverter, due to the feedback scheme. But be aware that the circuit is delicate and needs plenty of care.

On the other hand — if well made, you are certain to have a small amplifier of very high sonic quality. The interesting feature in this abbreviated Williamson, is the use of 6V6 as phase inverter. The low ri of this triode coupled 6V6 and the low load resistors of 10k Ohm, insures very fast pulse response and high HF roll off.

As it DC coupled via the plate of the 6SJ7, the input impedance is Philosophischer Irrtum - Strom & Wasser - Anticool (CD high, thus the same merits are insured for the 6SJ7 input amplifier. The 1uF coupling capacitors, on the other hand are on the high end. The LF roll offis around 1,5 Hz and this is most certainly too low.

This lead to DC recovery constants that will mess around in the high midrange and upwards. The 6V6 split load runs at about 8mA idle current, which helps, but not enough. I would swop to some n or so. The separate feedback winding improves stability in case of capacitive loading.

It is also possible to adjust the amount of feedback by means of the k potentiometer. This is also a good thing, as it gives a little help in matching the loudspeaker to the amplifier. Finally it is good to see that the input capacitor of the power supply is small, followed by a smoothing choke and only then a large electrolytic capacitor.

This prolongs the life of the rectifier, as well as reduce the ripple currents. The bleeder resistor of 13k Ohms, reduce the Voltage to fit the first two stages and the screen grids of the 6L6 output. This method actually improves the isolation, although at the price of a little higher ripple currents and power consumption. The resistor draws some 26mA. I am not sure that a serious manufacturer of High Fidelity these days, would dare to use a company name like this.

I am sure that even the rectifier is bored with muzak. The Muzak Corp. We always seem to get back to the Bell Lab. Well known classics and good OPT iron. These Dynaco circuits by Hafler and Laurent were almost one to one copies of Williamson, Mullard and GEC designs, but in my opinion the Dynaco copies are generally not very good engineering.

This is a very high quality amplifier made by the Klangfilm department of Siemens, Germany. Anyway Klangfilm produced professional amplifiers and similar gear for PA-service and broadcast. Cinema and theatre was their main market. The V is a master stroke. It is clearly made for long and stable service. These and paper in oil capacitors were rather common at the time.

Better safe than sorry. In the schematic I have left out the tone controls in the pre-amplifier and the networks feeding the in build meter for user service adjustments. The preamplifier is way too sensitive for modern domestic use.

If you own one or two of these amps, and you happen to be a dedicated vinyl fan, I would suggest to convert the pre-amplifier section in to a RIAA amp. The input transformer is of usual good Siemens quality and it will provide you with a sweet and delicate sound quality. The build quality is the usual Siemens, Klangfilm, Telefunken. This means high with care for the detail. Neither did Telefunken or Philips Sometimes a shield of mu-metal was strapped around the winding side, which is quite an efficient solution, although it does not look as good.

Right, lets talk about the power amplifier. The OPT only has two secondary windings, one is fixed for Ohms speakers, the other is a balanced feedback winding that we will discuss later in more detail. I like the idea of a single speaker output winding as it avoids the usual leakage losses in unused windingssadly this one is dedicated to 15 Ohms speakers only.

On the other hand it was not unusual that the copper resistance was quite high in the output transformers of former times. But too high copper resistance adds to distortion and negative dynamic regulation — Losses — and should be avoided if possible. The advantage of a separate feedback windings is that it does not force the amplifier into instability in case of capacitive loading from crossovers, cables and such.

Garage bands into Rock Stars. Recording studios into Hit Factories. Sound performance is still a long way off, and signal stability is still the best experience. However, the points above may not be enough for your experience. Our system also has a powerful feature called "Multi-room". By enabling the multi-room feature, you can control the music from anywhere in your house where there is wifi coverage. With music playing in each room, you can synchronize the music playing in each room, or have different music playing in different rooms at the same time.

Let's take a concrete example, if you are working in your study at night, all you need is a mobile phone, open our 4stream App, and you can play a love song for your wife who is cleaning up in the kitchen, plays a storytelling station for the child who is in his room, and a classical music for your mom and dad in the bedroom.

You can also set up a weekend party where each room plays a dance song at the same time, to get the mood up to the highest level!

We believe that by now, you have a good understanding of preamplifiers and have some initial ideas of what you need. Here is some more info to help you pick the right amplifier for the job. For the S10 preamp sound performance is similar to CD. So, if CD quality can meet your needs, S10 preamp is your good option. If your speaker is a passive speaker, then you need audio amplifier products.
