Rick Pa Stadel.. Thank you. I love soldering

Also, it might be worth asking a Moderator to move this to a new thread all your very own. 😉

Why? 😉

Gorgeous job on the soldering, by the way!

Soldering so good.. Should I use 2sc3421 2sa1358 before the driver and also 2sc4883 2sa949 as driver? I don't have an oscilloscope..

I have plenty of ONSEMI 2n5401 2n5501 I'll use them instead of all signal transistors...

Do these sound well? Would you describe the characters?
Which transes did you compare with?

ONSEMI 2n5401 2n5501

Good for general use 2n5401 2n5501 depending on circuit

More very nice work-product -- and the pics are great, too -- but unrelated to this MOSFET amp troubleshooting thread.

Cheers
