A compact and nicely wired PCB should decrease distortion even further. Equipped with precision metal resistors, high quality capacitors, this kit is ideal for high-power amplifier modules datashewt high fidelity quality sound that favors harmonics of type 2 tube sound. The claims for better and ‘automatic’ current sharing apply only to devices operated as switches, or where the two curves shown in Figure 5 cross over each other. When switching, V th and its temperature coefficient is not relevant because the gate voltage is invariably selected to provide ‘hard’ switching to minimise losses.
While the circuit can be and has been simulated quite readily with good results, this is no guarantee that everything will work as expected.
This will show that the threshold voltage falls as T j increases – a negative temperature coefficient. The secure code is incorrect. So a Class-A driver would need bias set to 3. Using just a pot as shown in P is absolutely forbidden with vertical FETs – a matched bias servo thermally coupled to the MOSFET heatsink is essential to prevent both thermal runaway and crossover distortion.
While this is true to an extent, it is obvious that it is not a general rule upon which one should rely in all circumstances. Figure 6 – Normalised V th Vs. Make sure your measuring equipment is decently calibrated!
For a better understanding, a simplified output stage circuit is shown below. Barely any third harmonic is seen.

Even this will not show the same effects as a true dztasheet amp – the nature of the distortion components will almost certainly be different.

Well, that is the easy route to take for designing an output stage. Based on the above, it is quite apparent that vertical MOSFETs can easily get into thermal dattasheet if the bias servo is not set up correctly. Don’t run any signal wire close to a power supply wire or the power transformer.

This point is made above, but is sufficiently important that repetition will not go astray. This must remain a very good reason to stay clear of these devices for audio, unless you are fully aware of the potential risks, and how to avoid them. While this scenario is not common in switching application, if the MOSFET is used linearly it is very real, and has caused problems in the past. And remember one thing – any output device can be precise if a proper design is found.

Amplifier quiescent current from the current level of precision adjustable resistance adjustment, DIY enthusiasts can adjust according to your liking different tones 6. At one watt, the distortion is not measurable at all, unlike with the class A driver. It is definitely not insignificant for a linear circuit as shown in Figure 4and especially so because of the relatively high transconductance of vertical MOSFETs. Log in or create an account. It is probable that the constructor will be forced to compromise, using a significantly lower quiescent current than suggested just to maintain a sensible heatsink size and temperature.
