Hi every one...
Is there som one that can help with a service manual on a ClearAudio Basic+ ? or tell the model of OP-AMP in the unit
Thanks in advance

Welcome to diyAudio Jan 🙂
If its an RIAA preamp then you are probably best posting the question over in the Analogue Line Level forum. This is for intros really.
If an opamp is an unknown then you can make a guess by checking the power supplies which will be on pins 4 and 7 for a single and pins 4 and 8 for dual opamp. RIAA stages probably use a low noise bipolar rather than FET device. Typically this would be an NE5532 which was the industry standard.

Please do not post more than one thread on any given topic or that topic to more than one forum. If you post to the wrong forum please ask us to move it. Thank you.
Just take a clear picture of top + bottom of the pcb. 99% of the time it's either a single dual op-amp with the RIAA in the feedback loop, or two dual op-amps with passive RIAA.
It is a dual. But I try with many other opamp but all getting very warm and burn the resistor "10R 1/4W" in the power in on the PCB
Trace out the pin out and make sure that you are not installing the replacement the wrong way around. Either that or it is oscillating. Standard duals have +Vs connected to pin 7 and -Vs to pin 4. I would check that first.
What op-amps have you tried so far?
Did you install sockets?
