Question Is the Toshiba 2SJ201/2SK1530 pair (Mosfet) suitable for output stage ?

I was wondering...

Are they lateral MOSFETs like Hitachi's 2SJ162/2SK1058 ?

Default Sound

The sound is wider and deeper.

Lets say, holographic. That's the best way to explain it.

Default 2Sk1530 and 2SJ201 and excellent combination

I have been using the 2Sk1530 and 2SJ201 combination in all my amplifiers for years. They are very fine performers when driven properly. I typically use 6ea 2SK1530 and 6ea 2SJ201 in each channel in a common source configuration.

I have a circuit diagram available of a amplifier I originally designed in 1992 that I used to have on my web site. This is a complex amplifier and not for those who believe totally in the keep it simple methods. It is likely not suitable for those starting out in this hobby. If anyone is interested I can put it back on my web site. I just need a little time to dig out the documentation. I have a limited number of circuit boards and the special power transformer available.

It's an interesting amp and complex is the word I haven't taken the time to really investigate all cool features but it looks well-done. It would be fun to see a picture of this amp or at least the pcb layout.

I'll upload the schematics for a while at my place (a couple of weeks).

Default Mosfet Power Amp

PERANDERS I appreciate you making the schematic of one of my MOSFET power amps available on your web site. If desired I can supply the PCB layout for both the amplifier circuit board and the power supply/control circuit board.

It will take me a while longer to redo my own web site before it is useable again.

Please send me the layout and maybe a picture and I will upload it. But I will only have links from here... for a while.

Use the email address which I have at my web pages (at the bottom of each page).

Ok thanks


2 more questions :
- are they lateral mosfets like 2SK1058/2SJ162
- are they thermally compensed
