For other grounded-grid single-ended design ideas of a class-A1 nature, see post numberwhere you find this circuit. Products may be manufactured at one of several qualified locations. How many watts of output power can we expect? 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. Xian and Mingxin actually photo. Since the rectifiers begin conducting at 0.

Here is an example taken from the GE data sheet for the wee tiny 12AT7. Click on images to see enlargements.

A nice feature to add would be an auto-bias and DC offset servo. Now, V – 60V is V, which divided by mA equals ohms, with 2. The grid current is still wasted.

Truer words have probably been uttered, but I’ve never heard them. The grid will begin conducting current and the current will augment the secondary’s negative swing.

Here is a workaround. High-quality, double-sided, extra thick, 2-oz traces, plated-through holes, dual sets of resistor pads and pads for two coupling capacitors. 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 could result in personal injury or death.

Radio transmitters that used power triodes and that ran in class-A2 used a small power amplifier to drive the transmitting tube’s grid. Just more satisfaction in the bag, there. It means that if you connect an 8-ohm load to the secondary, the primary will reflect a 3. We can lower the input impedance by replacing the cathode resistor with a constant-current source. There we have it.

No doubt, your first response would be to query the need for the extra diode and resistor that span between grid and cathode. They are configured in a garter-belt setup, where a DC offset naturally tends to correct itself. If we acknowledge and anticipate the severe load the grid will present, the rest of the class-A2, single-ended output stage is easy to design. The obvious danger is toasting the NPN transistor. Since we don’t use this symbol, you have to remember that the grid and plate define diodes with the cathode.

Dimension D and E do not include mold flash. How about sending the grid current into the secondary, rather than the primary? Often the safety diode is shown with the zener symbol, which is appropriate, as the diode’s breakdown voltage functions as a high-voltage zener. I’m sure you could charge double and still have happy customers. You must also remember that the grid can draw a substantial amount of current, when driven positive relative to the cathode.

Such statements are not binding statements about the suitability of products for a particular application. I have more to go. Thermal pad contour optional with dimensions D1 and E1. But as our concern is at the top of the line, it is accurate enough to use. Although this much heat is nowhere near class-A standards, it’s plenty toasty. Although a bit off topic, here is a class-AB Circlotron with a constant-transconductance output stage, the result of including the two 0.

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 the grid current. Here is a quick example, your high-voltage power supply puts out only Vdc, which is why you are thinking about using class-A2. What does that mean? 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. Now, 8V divided by 0.

Of course, not by that much, but at least the grid will not be wasted.

Contour of slot optional. At idle, not much. Seldom have I mentioned class-A2, mostly back in the ‘s. Now that I look at it, I see that the bottom switch’s contact should attach to a small-valued capacitor to ground, say 0.

Second, your shipping was lightning-quick.

Mold flash shall not exceed 0. To purchase, please visit our Yahoo Store: Case Datasheeet tr td off tf Fig. One workaround has been offered that uses the grid current by sending it into the output transformer’s primary.

It also provides greater creepage distance between pins to meet the requirements of most safety specifications. The following is a simple, MOSFET-based, single-ended Circlotron that idles at 2A, so 16W into 8-ohm loads is possible, as the peak output current swing equals the idle current in a current-source-loaded single-ended output stage.
