I have only 2 pairs of EXICON lateral in my SPICE.
ECF10N20/ECF10P20 and ECF20N20/ECF20P20

I have done some testing using ECF20N20 in SPICE.
If I am to believe the models and results
the ECF20N20 is a fantastic lateral mosfet!
The distortion is very low in compare with HEXFET.
These ones are specially made for Audio.

Click the image to open in full size.
EXICON ECF20N20 is in TO3 and takes no less than 250 Watt

thanks for this advice. I will try to get P-spice parameter by profusion.

To Mr.Tiefbassuebertr,

I have bought 16 pairs of 2SJ50/2SK135 because of the attached mosfet amp which I owned in 1982. I want to make a new mosfet 100W amp for my ineffective speakers AR3a.
Do you have a better schematic to use than the attached.

Just for the record. I have Luxman L58A which sound very good , but suffers for the lack of power ( only one pair 49/134 Hitachi per channel).

Do you know anyone who could help me on this one? Have already asked this question here without luck.

find a better schematic.
556a as input
corrupted Mirror in the VAS load
Mirror without cascode
VAS directly driving output FETs

All these need attention.

I agree, Andrew .. but this would work if r9 was 6.8k-10k, low voltage PS or better input trannies. Still, proper drivers and a REAL balanced VAS would be more musical and durable. Here is an example of a commercial offering that does the same "cheap tricks" (HH amplifier co.) HH Amplification - Speakers

But AndrewT - you checked the schematic and found some things to be done better - this is why I am asking? I asked if anyone has a better schematic where it is possible to built a mosfet amplifier with 2SJ50/2SK135 and proper drivers. I have tried to change the 556a with 2SA970 on the attached circuit, but just on the computer.

I know that the schematic has some difficulties. - Could you or anyone else come up with a usefull and well sounding amplifier - a amplifier to be built by a not educated audio engineer??? as optician I have made several DC amplifiers with bipolar power transistors - and with luck.

I have tried with one Borberly mosfet amp, many components, may be too complicated that we looses the the clean sound??

A simple good circuit for double pair of 2SJ50/2SK135 is what I am asking for.

With the 2SJ50/2SK135 ANY BJT forum amp will work with a few mods. I happen to have a whole pile of lateral projects here: HFS /WEBSITE/PDF1/Electronics/Projects/Audio_amp/Mosfet_25-1kw/

In fact , download the "subzero" amp (similar to yours) by Dr. jagodic .. he is a college professor and all his designs are soundly based and tested. Most are very well received by the European DIY'ers.

Thank you - amplifiers designed like the "subzero" could be the one I was looking for. Have you tried the circuit? I assume that the "zero" could be built with two pairs instead of three ( power fets)?

It is quite some collection of power fet amplifiers you got there -

I have a very well sounding bipolar amp without global feedback - the amp "The End MKII" has in comparison with other amps "beaten" most of the so called "high end" amplifiers, exept some very expensive amps from Audio Research. The controll of the woofer from bipolar outputs seems better than from power fets, but the mid- and high midrange and frequences above 8-10kHz sounds better from power fets (I think) - I would like to try and add 2 or 3 pair of the Hitachi's in a good circuit, just to "see" if I can get almost the same woofer control from the fet's.

It is difficult to achieve everything within one amplifier!

FYI: Toshiba 2SK1529/2SJ200 reached EOL
I read by post #1:
When I was asking for quotation, Avnet Singapore told me that Toshiba 2SK1529/2SJ200 are no longer orderable
this means for me, all MOSFET's listed here by post #1 should be not used and should avoid for new design's.
For new design's only N-Channel MOSFET designs (NMOS) should be used.
