Six weeks, which is Sony's time frame. Hopefully, unless it is still under warranty, you have put a 'stop loss' amount on the repair cost. Otherwise you leave them an open ended repair order, which never works out to your advantage.
Manufacturer Repairs? What is a reasonable time?
I sent a solid state amp back to the manufacturer in the USA on March 16 for a minor repair - one channel input not working - despite 4 phone calls and 4 e-mails - he hasn't even started the repair. Doesn't respond to emails but does answer the phone and says he is busy and is alone. I Will not identify him yet, since I'm not sure what the "norm" is, since I have always been thoroughly spoiled by Bel Canto, Atmasphere, CJ, AR, acoustic Zen, Cambridge, EAR, who respond immediately and usually have my unit back in 2 weeks. So when do I start to play "ugly", realizing that the economy is bad and manufacturers may be struggling?
