I would like to know what kind of maintenance that needs to be done on amplifiers. I'd like to keep mine around a long time. Please also advise on thing to be looking for as far as signs I should be looking at.
Thanks!

Thorough cleaning is a good idea.  With ceramic tubes, the air flows through cooling fins that surround the tube body and the air channels are not very wide.  Dust will restrict the air flow over time, reducing the cooling of the tube body.  I take my tubes out once per year and thoroughly clean the cooling fins using a brush and compressed air.  Glass tubes are less of a problem in that respect, but it's still a good idea to keep the blower or fan clean.
