Sending a 110 lb amp to the manufacturer for cleaning/calibration. Good idea? How to ship?

Hi All,

So I reached out to Simaudio as my amp (Simaudio Moon Titan HT200 5 channel) is getting a bit long in the tooth. It performs truly flawlessly and is just beautiful and barely even gets warm after running all day long. I was just more curious than anything about lifespan, etc. Simaudio replied right away. They said all the units they'd manufactured since 2001 are still "active". However they did recommend sending it to them (if I could be without it for a few weeks) for "cleaning and calibration".  

Couple of things, I can't even go 1 day without this unit. But beyond that just the thought of packing this thing up and shipping literally makes me cringe. I'd certainly pay extra if there was some way to avoid UPS/FedEx or any other means like that. Any recommendations and have any of you ever done something like this?

Would appreciate any advice. Thanks all in advance...

What is there to calibrate in a SS amp?

Many amps, both stereo and mono, need manual adjustment of the bias.

This post makes me happy that when I had to send something back to Julius at Audire, he told me how to unplug the right channel transistor laden heat sink, in order to just mail it. Strangely, there was no problem. I had a bad Radio Shack Balanced to RCA adaptor.

Bias makes very little difference unless amp is running hot. (If you have a friend that can do it in your house, okay) The original capacitors in my 42 year old amplifiers still test good (5% to +20% of original value). Good quality SS equipment typically last 40+ years, even if they have been driven moderately hard. Again, if it ain't broke, don't fix it. The reason there are very few QUALITY used amps for sale is the shipping companies. (You know who I'm talking about)

The amp will most likely need new electrolytic caps throughout based on age. Once replaced the amp will indeed sound better. These do dry out over 20 years are don’t hold to spec any longer.  
This will cost, but it will help you keep the amp for many more years. It is always risky to ship so driving it there would be better. 
I would not bother with cleaning or biasing unless you first replace the old electrolytics. The manufacturer is most likely on top of this as part of the plan.
