Charles, Your experience has been fine, but is by no means universal. A major hurdle, IMHO, is matching the tube amps output impedance (curve) with the speakers frequency response. Not a simple issue for most, but especially for a tyro who has no experience with the wide range of possibilities available to him and can easily chose an amp that will sound like crap just because it is a tonal or electrical mismatch. He will need guidance by some one familiar with his speakers, his environment, as well as what he expects tonally. Just determining the type of amp he will enjoy most is no small task. A 300b amp is just one of many possibilities which will work fine.
Maintenance wise, the only really major issue, apart from the quality of the units themselves and their ability to provide long service with out premature failures, is, if one is not a techie and has an amp which blows out a resistor when he has a power tube failure has to truck the amp off to a repair shop or mail it somewhere for repairs. Simple repairs, not too expensive, but many tube amps are very heavy and a PITA to haul about. Now if he were a techie he could simply replace the resister himself. No big deal.
I think telling someone to just 'jump in, the waters fine', should only be given to someone to who has learned about the water, i.e. its depth, temp, and any hidden currents, so they will not just find themselves over their head and freezing after they jump in. :-)
FWIW I have several high power tube amps which are or have been, ultimately, fine boat anchors. ARC, Sonic Frontiers, Mesa, Cayin, and some I've probably forgot.
