Quad 520F output transistors??

[andjur78]

Hi, I have a Qaud 520F with some shorted output transtors.
Apparently it has been worked on by a tech before and he gave up.
The transistors read as RCA devices "17556" Are there any common known equiavlants.eg MJ15003?
Thanks.

Hi;

MJ 15003 is the correct type. These replacements are also used by QUAD when they carry out repairs. Beware of faked MJ15003`s!

kind regards,
