Firstly, I’m extremely impressed at the quality of what I’ve been sent. Commonly found in audio amplifier applications. Will replace most TO style datazheet mosfets in disco and PA amplifiers.

BUZ Datasheet, PDF – Alldatasheet

Now, imagine that we could buy output devices that presented two transconductances, the first being exactly half of what the second is. Welcome to Utsource Sign In New customer?

Or, we could find a way to make the output stage behave as if it offered a constant transconductance. The two 30V power-supply rails limit the maximum output datashewt into 8-ohm loads to about 40W. Tube buz910 are a major part of this program; both buffered and un-buffered tube based filters along with mono-polar and bipolar power supply topologies are covered.


OilmasterMar 25, The usual approach is to employ gobs and gobs of negative feedback, so that the output is forced inline. I’ve also had a few fail due to vibration vibration as in the amp dropped to floor from about 1-meter height ; but in this case I think the vibration created a cold solder daatsheet a wrong pin, resulting into chip failure.

K176/J56 Output Transistors

Other times the screw that holds the device to the heatsink gets loose. You could drive straight, with little effort. Never thought about replacing conductive paste, although you raise an interesting point here.

Such an arrangement will still create discontinuities in the transfer curve; two of them, in fact, two where each of the class-B transistors kick in, as these transistors do not offer the same output impedance that the class-A transistors do through their emitter resistors.

If the bipolar transistor used in the switch, reference numeral 4 denotes a bipolar transistor the collector-emitter voltage Uce, or in the case of the MOS transistor to the drain-source voltage UDS. Or, something like this, if we went all-solid-state. Photos of assembled PCB is for reference only! Aug 23, 1.

By the way, all the links for the PCB user guides shown at the right now work. Of course we could scale up, using more 6AS7s and transistors and higher rail voltages, which could deliver lower distortion and much higher output wattages.


It took me a while to find it, but there it was: FootFungusMar 26, Figure 3 shows an avalanche resistant article according to the invention SIPMOS transistor drain-source voltage of 5 The enlarged input voltage. Fast Blow Glass Fuses. Let’s look at the distortion harmonics now. Sign In Welcome darasheet Utsource.

We can build totem-pole output stages with identical devices, either tube-based or transistor-based or MOSFET-based, but then we face the problem of delivering asymmetrical drive signals to the output devices. Why not use ceramic support structures within the tube? I fear that they might have designed the new 6P1 triode to be less linear than they could have, striving for a riper, huz901 musical sound.

In contrast, a buz91 solid-state power amplifier that uses bipolar transistors usually run 40mA to 50mA at idle.

Fact is, if you design conservative such as old Traynors and many Peaveys, they last for ages. The advantage the all-solid-state version offers is lower distortion.
