The problem is that all output tubes actually incorporate these extra components inside their glass envelope, as they are intrinsic to the triode’s functioning, although the schematics never show them. There we have it.

The workaround is to make them ourselves. No signal gain is provided, so a hot balanced line stage or an internal input and driver stage will be needed. If you enjoyed reading this post from me, then you might consider becoming one of my patrons at Patreon.

Dimension D and E do not include mold flash.

Fatasheet, Mar This datasheet is subject to change without notice. Wanted to let you know that this is simply the best PCB I have had in my hands, bar none. The cathode follower must be robust enough to pass the required grid current. For example, I have never seen published the positive grid-lines for a B triode, which would come in handy in designing a class-A2 output stage.


Thus, the driver tube will see a lower cathode-to-plate voltage than the power tube, which means that we run the risk of irfp4g0 driver tube entering positive grid voltage. For example, a B published current limit is mA, so 20 would be needed to get to 2A. They dataxheet not, as the rectifier exhibit an internal resistance of about 0.

Dataeheet course, not by that much, but at least the grid will not be wasted. Click on images to see enlargements. Such statements are not binding statements about the suitability of products for a particular application. Looking forward to building the Aikido, will send some comments when I’m done! I received the Aikido PCB today – thank you for the first rate shipping speed.

Products may be manufactured at one of several qualified locations. Visit the GlassWare-Yahoo store today. High-quality, double-sided, extra thick, 2-oz traces, plated-through holes, dual sets of resistor pads and pads for two coupling capacitors.

I didn’t draw the dashed line between the two switches, but the two work in unison. This omission was probably a mistake on my part, as the problem of positive-grid-conduction is a large one. You must also remember that the grid can draw a substantial amount of current, when driven positive relative to the cathode. Here is an all-tube version. Although this much heat is nowhere near class-A standards, it’s plenty toasty.


Please contact authorized Vishay personnel ircpg40 obtain written terms and conditions regarding products designed for such applications. Returning to this circuit, in theory, the 0. In other words, although the inter-stage signal transformer will out perform a coupling capacitor, it is not a slam-dunk or easy-to-implement solution. One workaround has been offered that uses the grid current irfpg400 sending it into the output transformer’s primary. How many watts of output power can we expect?

In short, class-A2, whether in a single-ended or push-pull amplifier, requires much more thought than most expect. The grid current is still wasted. The two floating 20V power supplies should be rated for at least 4A of current flow. We can expect a tad less due to losses, such as datasgeet and secondary DCR and core losses, so 10W to 11W would be a reasonable guess. If you have been reading my posts, you know that my lifetime goal is reaching post number one thousand.

And this is only under normal operation. Thermal pad contour optional with dimensions D1 and E1. I’m sure you could charge double and still have happy customers. For more information, please visit our Web site: Here is a workaround.
