Is it an option to see if you can find a junk donor unit, perhaps even one already mostly stripped for spares already to save on outlay?


I've been trying to but individual sellers won't split A/V amps (even when described as "junk") in parts.

It costs money to dispose of electronics in Japan ($5 to $50 or more depending on size/weight/type) and selling the whole chassis, even for cheap, is a way to get rid of it and make a little profit instead of a loss.

I might give ONKYO -- the new owner of Pioneer A/V -- a try!

If the regulator goes bad once, it will one day happen again w/ the replacement as well.

Might be easier finding a technician to look over the regulator and find what I assume might be a few burned out parts that would be easier to acquire off the shelf.

Can you take a look at the board for any bulging or leaking capacitors? Or even burn marks on the board.

It looks like there are two fuses and several electrolytics on AWX7310.

Haven't found any :-(

ONKYO will not sell me the regulator board "because it's a risk for general public".
And since I can't fix the regulator, they will not sell me the replacement foot even though they have it in stock.

The Japanese business mind will always remain a mystery to me (but the state of the economy seems to agree that it's not the sharpest).

Is there a business that could help order it for you? An Onkyo dealer maybe? Surely somewhere in Akiba could help? Assuming it's somewhere within reach, or courier?

I'm assuming one or more have just dried up then. I was recommended the Atlas ESR70 by a member here for situations like this, but if you have a soldering iron I'd just gamble that replacing the caps would resurrect this unit.

The A/V amp ended up in the trash (with recycling Japanese "B" stickers" since it's above 10kg) because Pioneer/Onkyo wouldn't let me replace the power board and chasing a replacement unit or finding spare on the 2nd market was not making a lot of sense (lots sold as "junk" or "as-is", might have the same issues!).

I'll use the extra 2ch/Zone B on the McIntosh amp to power a 2nd room in stereo instead.
