Default Output Mosfets

Anyone can suggest me good and cheap mosfets to use as audio output devices, suitable for paralelling, with a complementary pair if possible ( N = - P). I just give it up on using the IRF640.
TO-3 and TO-220 types are better for me, I just don't have any TO-3P heatsink, and have lots of TO-220 and TO-3.

I really apreciate any help!

I have a box of 2SJ50 and 2SK135 (37 pairs) for sale, not cheap though...

I have also IRF ??? 8A, 200 V in TO-3, both N- and P-channel. They are new and never used. 4 pcs of each.

Ok, A little bit more specific:
I'm looking for something like 7 to 15 amps, and quality is not the 1rst requirement, I just want to try make it work, and what is that TO-3 IRF?

And thanks for your help!

Default what is that TO-3 IRF?

IRF is the International Rectifier MOSFET family.

TO-3 is the metallic body type.

HI Peranders,

I have a few 2SJ50 and 2SK135 as well, do you know of any good circuits for future reference that uses these?
