Soundstream Reference 705s problems - Page 4

I currently only have OP275 and OPA2134PA in stock. I'll solder in a socket and put in one of these chips, see what happens.

I replaced U1 by a socket and another NE5534, amplifier still does not work properly.
Now one of both channels wasn't even producing sound, instead of very weak.

Stupid me, U1 is a NE5532 I now realise, not 5534
Will have to check whether I indeed used a 5534, in that case I'll test the amp again with a 5532 later on, when I go back to my father's place. Hopefully I did not damage anything by putting a wrong chip ? How about the chip itself ?

Perry,

A thousand thanks, replacing the NE5532 by another NE5532 did it !
The amplifier powers on normally, nice idle, no POP ! and nice sound.
My friend, for whom I bought the amp, is very happy ! Got a nice amp with no previous damage / repairs in very nice exterior condition for a good price and almost zero repair costs.

THANKS !

Fred
