Purchasing parts from Onkyo????

edgelgil's picture

Hello everyone, I received and Onkyo A-5 amplifier from a friend after he let the genie out of the case.
I opened the cover and found the primary output channel board had some rather smoked components.
I would like to thank the member who uploaded the service manual for this amplifier. Ok, I call and emailed Onkyo, they send me to a tech shop 500 miles from my shop. Called the shop for parts and no deal. I called the service line to Onkyo, of coarse their main service distribution is on the east coast.
My point is, I trying to buy the board loaded with components, I have already ordered new output transistors, been digging for some other components, incase I can't get the board.
Has anyone here had any luck getting parts if your not part of the elite service centers, or have close friends associated to help ascertain parts?
I'm a master CET and PMEL professional , kind of benign to send my equipment out to a service shop.

Re: Purchasing parts from Onkyo????

According to HFE site, the A-5 is well over 10 years old. That being the case, I would doubt Onkyo has any complete circuit board assemblies available. I worked for a US pro-audio company for over 20 years and we only sold complete boards to authorized service agents simply because it avoided inexperienced technicians blowing up parts then wanting refund / credit / exchange. Similarly, we had complete stuffed PCBs available for roughly four years after model was discontinued. Discrete components availability was dependent on how many models used a particular device. All this being said, I suggest a complete tear-down and refurbishment of the entire unit. Even a smoke damaged, burnt PCB can be resurrected --- worst case, scan the traces, lay out a new one, have a board house fabricate a replacement unit. Most all semiconductors can be substituted so getting spares to rebuild product should be viable. Check out https://alltransistors.com/ for data sheets and specific parameters as well as substitutes. Digikey, Mouser, Newark and many other vendors offer through-hole components, vintage spare parts specialists exists as well. A-5 and later A-05 are very fine models, worthy of complete restorations.

Many manufacturers only want authorized service centers to work on their equipment, and will not sell parts to individuals or owners, even out of warranty.
