I have a BM6500 with 2 dead output transistors.

I have found these

https://elektronik-lavpris.dk/p77680/bdv64b-pnp-darl-100v-10a-125w-to218/

https://elektronik-lavpris.dk/p77681/bdv65b-npn-darl-100v-10a-125w-to218/

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 :)

Correct BF transistors here:

https://www.beoparts-shop.com/product/transistor-bf858/

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