I have a BM6500 with 2 dead output transistors.
I have found these

But they are rated for 10A, while some searching online, claims that the original "specially adapted sample" from Philips, are 12A ?
Is it safe to replace all 4 with the one I have linked to ?
Also, what is the best replacement for the 4 BF858 transistors ?
Thanx

Oh, and I forgot. The 2 0.22Ohm 1W output resistors are also dead, has anyone found good replacements for those ?
Hmm, after reading the specs more specific, it seems the linked transistors are also ic value of 12A and the 10A I read wrong, is the collector current.
So I think I will buy them and see if they work :)

Are these a good replacement ?

Correct BF transistors here:

Use the contact form - also for the darlingtons and resistors - they are not yet online.
