Truer words have probably been uttered, but I’ve never heard them. Returning to this circuit, in theory, the 0. Case Temperature tr td off tf Fig. All of the grid lines shown are for zero dataeheet positive grid voltages, which explains why they don’t look normal.

The grid swings in phase with the cathode, so a negative feedback loop is in place, which means that the cathode must see much larger voltage swings to bring the output stage to full power.

There was a time when I would not dare show such an extravagant design, but now that we live in an age of 1W OTL power amplifier that use four B output tubes, this design seems almost beer-budget. While playing music, on the other hand, we face potential problems. Click on images to see enlargements. For example, a B published current limit is mA, so 20 would be needed to get to 2A. We find the required bias voltage by traveling down the mA fatasheet line until we hit V, which appears to be at about Vdc.

We can expect a tad less irfpb40 to datazheet, such as primary and secondary DCR and core losses, so 10W to 11W would be a reasonable guess.

The two floating 20V power supplies should be rated for at least 4A of current flow. The inter-stage signal transformer must be driven by a robust driver stage, as it will relay the drastically lower positive-grid impedance to its primary, which if capacitor coupled, will prove a giant step sideways, as this capacitor will charge up, but cannot create blocking distortion, as the transformer cannot pass DC voltages, but the excessively charged up capacitor can throw off operating points in the driver circuit.

I have a few things to say about it.

Interesting, if a bit obvious. Customers using or selling Vishay products not expressly indicated for use in such applications do so at their own risk. I remember Richard Feynman using the small-case delta to denote that a variable was being “held constant,” thus. I bought an Aikido stereo linestage kit from you some days ago, and I received it just this Monday.

Since the rectifiers begin conducting at 0. Seldom have I mentioned class-A2, mostly back in the ‘s. In other words, a V NPN transistor will die. It’s not a bad idea, but the tube must get its own floating heater power supply and it must be robust enough to pass dataeheet grid current.

Here is an example taken from the GE data sheet for the wee tiny 12AT7. A nice feature to add would be an auto-bias and DC offset servo. Please note that some Vishay documentation may still make reference to the IEC definition. Although a bit off topic, here is a class-AB Circlotron with a constant-transconductance output stage, the result of including the two 0.

Although this much heat is nowhere near class-A standards, it’s plenty toasty. Contour of slot optional. If we subtract the push-pull functioning, we are left with a single-ended split-load phase splitter—oops, I mean a single-ended Circlotron. Imagine a 12AX7-based driver stage. Vishay makes no warranty, representation or guarantee irfog40 the suitability of the products for any particular datashet or the continuing production of any product.

The grounded-grid amplifier topology offers greater high-frequency extension than the grounded-cathode amplifier, as it sidesteps the problem of Miller-effect capacitance, but at the cost of having to drive the low-impedance cathode rather than the high-impedance grid.

No license, express or implied, by estoppel or otherwise, to any intellectual property rights is granted by this document or by any conduct of Vishay. I have seen underscored or was it an over-scored symbols used in old electronic textbooks to denote a variable being held constant, but that can mean “the lrfpg40 of.


I didn’t draw the dashed line between the two switches, but the two work in unison. We can lower the input impedance by replacing the cathode resistor with a constant-current source. For those of you who still have old computers running Windows XP bit or any other Windows bit OS, I have setup the download availability of my old old standards: Thank you, regards Gary Mr Broskie, I bought an Aikido stereo linestage kit from you some days ago, and I received it just this Monday.

The two potentiometers set both the idle current and the DC offset. Imagine if a friend sent you the following schematic and asked for your comments.

What does that mean? At idle, not much. For other grounded-grid single-ended design ideas of a class-A1 nature, see post numberwhere you find this circuit. Indeed, you would worry that these extra parts will result in greatly increased distortion when the grid is driven positive relative to the cathode, as the diode will be forward biased and begin conducting, which will impose a much lower load impedance to the signal source.

Except as expressly indicated in writing, Vishay products are not designed for use in medical, life-saving, or life-sustaining applications or for any other application in which the failure of the Vishay product datashset result in personal injury or death. For about twice as much, you can buy a 4. Of course, not by that much, but at least the grid datashedt not be wasted. Such statements are not binding statements about the suitability of products for a particular application.

Datashfet purchase, please visit our Yahoo Store: But as our concern is at the top of the line, it is accurate enough to use. I have patrons to go.

You must also remember that the grid can draw a substantial amount of current, when driven positive relative to the cathode.
