no matching needed

they're "just" cascodes so you can use any bjt with at least , say , 60V voltage rank

Jumping on this old thread..

Hi all,

I do have MJE 15032/15033 in the drawer... use them on shop for better suited ?

Cheers,

Max

Feeling more Zen now - vielen Dank Zen Mod.

No heatsink needed I think

Edit:

For reference MJE15032/15033 is BCE , BD136/140 is ECB (ie BCE rotated 180%)

no need for hsinks
