See my other reply! They are very difficult to stabilize without some sort of dqtasheet servo. Alan I don’t think the problem is with the transistors.

I guess I will not use SJ for this circult. Then choose a final capacitor 1. Two pairs were used per channel. Go to this site: So you need a temperature compensation for the Sj,usualy a transistor multiplifier BE mouted in thermal contact with the output devices.

Check the devices data sheets. Burning is typical unstable Circuit.

Produst description The Field-Effect Transistor FET is a transistor that uses an electric field to control the shape and hence the conductivity of a channel of one type of charge carrier in a semiconductor material. I rebuild the whole thing and this time I used around 50ma per pair, i. Gate threshold voltage Vgs th.


I have my eyes without leaving the current meeting, the current then flutuated from 75 to as high as mA.

Also good for outputs for amps in the 25W size. Because these two terminals are normally connected to each other short-circuited internally, only three terminals appear in electrical diagrams. Sorry for my “english” I think that you don’t have it as with the Sj is not nedded I set the bias current to 65 milliamp per pair.

I had a similar problem a month ago and it drove me crazy. I leave it on for a while feeling OK. Surely there is no bias control circuitry as suggested to Santos and MLLoydl. Amp fixing groman Thanks for the advice – akltam Hi Alan You’re right – those voltages should be be no problem.

It shares with the IGBT an isolated gate that makes it easy to drive. Is this the case? In fact that resistor together with the input capacitance messured in pF, see datasheet, forms a RC-lowpassfilter, that makes the fast MOSFETs somewhat slower, that gives a lower Open Loop Bandwidth, and so it can make the amp more stable!

FETs are unipolar transistors as they involve single-carrier-type operation. I suppose you have no oscilloscope.

Groman had a real good point about the bias voltage. Any experience on 2SJ and 2SK?

NT – akltam I datashee suggested that some of these devices are pretty unstable in the first hours. Put an small plastic capacitor parallell over feedback resistor goes from output to inputstage pF or pF See if it gets better if so you have found that amp was unstable. And would try the parallel cap as suggested.

Most other devices for example HexFETs don’t have a zero tempco until the drain current reaches the several amps region – so you’d need a bias control circuit!

And also if current differ from high to low to high.
