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

compressed air , take outside of course , then go back inside rub one out then hook back-up . problem solved 

MC has given you sage advice.  My vote for post of the month! 

Think of those circuit boards, connectors, etc all vibrating for hundreds of miles.  Then those potholes.  Electronics just love potholes. 

I think the potential for damage far outweighs any benefit that could exist.

If someone was bent on checking bias and cleaning--do it yourself!  With some basic equipment it is not difficult.

WOW! First I want to thank all of you for taking the time to offer great advice on both ends of the spectrum. Great arguments both for and against, what to do????

I feel like getting total peace (Piece for all us Maidenheads :) of mind of having the high end pros at Sim do their thing and get the green light and gain the confidence knowing she's got a clean bill of health...

However I keep coming back to "if it ain't broke", and the disconnecting, lifting (and I have decided if I do have this done I am doing the road trip thing, as yes @jl35 I completely trust Sim, I would love to keep forever, and I do enjoy driving), going without really just so does not at all appeal to me...And thank you @philiptamarkin for the White Glove info offer. And thanks @gochurchgo for the offer to assist but I'm on the other side of the country in NH...

I will follow up when I make the decision (still waiting to hear back from Sim on the address and if I can drop it off in person)...

Regardless you all have provided great info and some good laughs and I can't thank you All enough for taking the time to help. I feel like this thread represents the best of what this site is all about, at least for me anyway! Good stuff! You guys are awesome man!

Lots of great advice so far; but, here's some first hand experience to consider...

Many years ago my house took a direct hit by lightning and it fried many things, including my Sim Audio amp. I took it to a local Sim Audio dealer who then sent it back to them (in the original box). When it came back it sounded significantly better than before the lightning strike; so, make of that what you will.
