Very high output power and bass performance.. Response time and midrange performance very good.. Front side black painted aluminium. Two pre out with on/off button. Phono level input and quality preamp. Potentiometers and Input selector buttons are poor quality. Distortion in high volume level.



re: A-8087

I bought this amp new way back in another time. Lately it seems to distort, cut out, lose a channel and then operate ok for a while then repeat the distort, etc. Any ideas on what I can do or where it can be repaired?
thanks in advance for your reply.

re: A-8087

I have an Onkyo A-8048V that sat unused in a box for nearly 10 years. I sent it to college with my son, and it started to experience the same issues you describe in your 2016 post.

Were you able to get the issue resolved?
If so, what was required to fix it and what did it cost you?


re: A-8087

The same problem, not solved several times by Onkyo service. It is construction/production defect.

re: A-8087

Thank you very much. I like the sound of this amp, mine is from 1987 and the volume and balance potentiometers are failing. With the info from this manual, I will be able to fix it.
