Audio Repair - How long do you expect to get yours fixed?

It takes as long as it takes. With uncommon parts, a repair shop might be waiting for a week or two or more if on back-order and/or coming from overseas. Anything from china or Japan takes a minimum of one month, often two months. 

Thanks for your response.
In my case, it's been over 4 weeks since I dropped them (one power amp, two preamps, and one turntable) off.
So far, I don't know whether the service shop even started to take a look at them. When I asked about them, the only thing I heard so far is that they will take a look at them soon.
This kind of practice is usual?
When I first asked how long it will take a look at them, the service told me a couple of weeks.
Well, I will wait another week or so, and see what happens.

You should find another shop!

I had an amp I sent in for a transistor replacement. An item he had in stock. I was told about three weeks. It took about three months. No big deal to me. He kept me posted.
When one man is repairing for a living he usually has some in repairs in the Que line and not all repairs go as planned. Not all days go as planned. Hope things work out well for you.
