The dashed lines reveal the amount of current drawn by the positive grid voltage. I wish everyone did business like you. Here is an example taken from the GE data sheet for the wee tiny 12AT7. The grid current is still wasted. All of the grid lines shown are for zero and positive grid voltages, which explains why they don’t look normal. Interesting, if a bit obvious. These dimensions are measured at the outermost extremes of the plastic body.

Well, your worries are well founded. 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: 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.

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. Indeed, we could have used the following triode symbol rather than the conventional one. You must also remember that the grid can draw a substantial amount of current, when driven positive relative to the cathode.


Second, your shipping was lightning-quick. The two floating 20V power supplies should be rated for at least 4A of current flow. The top of primary sees a fixed V, but the bottom end sees voltage swings down to V and up to V.

Obviously, the further left it goes, the less accurate we can expect it to be. It means that if you connect an 8-ohm load to the secondary, the primary will reflect a 3. I have more to go. For other grounded-grid single-ended design ideas of a class-A1 datadheet, see post numberwhere you find this circuit. The obvious danger is toasting the NPN transistor.

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. Of course, not by that much, but at least the grid will not be wasted. For about twice as much, you can buy a 4. I do plan on remaking all of these programs into bit versions, but it will be a huge ordeal, as programming requires vast chunks of noise-free time, something very rare with datashewt running about.

Here is an all-tube version.

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. Looking forward to building the Aikido, will send some comments when I’m done!

Since these rectifiers effectively clip the DC signal sent to the right OpAmp, dqtasheet can implement an auto-bias scheme in spite of the class-AB operation. Since the rectifiers begin conducting at 0. Here is a quick example, your high-voltage power supply puts out only Datasheeet, which is why you are thinking about using class-A2. In that brief period of time, the primary can erratically swing thousands of volts, as the primary impedance has risen irfg40 near infinity.


Here is a workaround. Firstly, I’m extremely impressed at the quality of what I’ve been sent.

Although a bit off topic, here is a class-AB Circlotron with a constant-transconductance output stage, the result of including the two 0. 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.

Xian and Mingxin actually photo. We can expect a tad less due to losses, such as primary and secondary DCR and core losses, so 10W to 11W would be a reasonable guess. In other words, a 12AX7-based cathode follower will not be of much use in driving a power output tube’s grid positive.

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.
