New member + Replacing 2SK133/135 2SJ48/50

[resolution]

Hi DIYA'ers.

I'm a new member to this forum having stumbled across it looking for something else far less interesting.

What a breath of fresh air! Having spent the past month looking through some of the posts here I'm very impressed with the quality, dedication and passion expressed within this group.
I'd also like to say well done to diyAudio for the group itself. Being able to attach drawings & links with ease + a good search system makes some other groups look quite lame.

I've spent the past 20yrs in pro audio as a recording studio tech. In this time I've built a few amps, loads of pre's. Mic amps etc.
I've now moved into home automation & AV as the money is a bit better and the hours are kinder. (It matters at my age)

Now to my question.
I'm looking for recommendations on replacing these MosFETS with more modern and "compact" equivalents.

The main criteria being compact. I'm looking for your recommendations on fast, quality, SOT-93 or TO-220 devices.
I'm currently in the process of re-designing an old amp of mine from about 15yrs ago to fit into a much smaller enclosure.

I also would like to see a dedicated Class D forum on DIYA. Where do I tick the box for my vote? 🙂

Good luck to you all and thanks in advance for your help.

Do tell 😉

Can't help you with the components, though we are working on the Class D forum, but our tech. Audiofreak, is currently recovering for a while after the server move...

Hi pinkmouse,

I think was looking for some simulation sw that could import a Powerlogic netlist if my memory serves me correctly.

I did say it was "less interesting"🙂

You can use the plastic equivalents...2SK1058 / 2SJ 162 .

Thanks Jorge,

That great news as it means I don't have to change much.

Kind regards
